What are the solutions of the equation x4 – 5x2 – 36 = 0? Use factoring to solve. x = ±2 and x = ±3 x = ±2i and x = ±3 x = ±2 and x = ±3i x = ±2i and x = ±3i
Answer:
[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]
Step-by-step explanation:
So we have the equation:
[tex]x^4-5x^2-36=0[/tex]
Let's let u equal x² so:
[tex]u^2-5u-36=0[/tex]
Factor. We can use -9 and 4. So:
[tex]u^2+4u-9u-36=0[/tex]
From the first two terms, factor out a u.
From the last two terms, factor out a -9. So:
[tex]u(u+4)-9(u+4)=0[/tex]
Grouping:
[tex](u-9)(u+4)=0[/tex]
Zero Product Property:
[tex]u-9=0 \text{ or } u+4=0[/tex]
On the left, add 9. On the right, subtract 4:
[tex]u=9\text{ or } u=-4[/tex]
Substitute back u:
[tex]x^2=9\text{ or } x^2=-4[/tex]
Take the square root:
[tex]x=\pm 3\text{ or } x=\pm 2i[/tex]
And we're done!

Explain how you can use grouping to make multiplying three factors easier.
Answer:
no To multiply three factors, we first multiply two of the factors together. Then we multiply the product we get by the third factor. Since multiplication is commutative, we may multiply numbers in any order.

A shirt that you want to buy costs $15.50. You can use a $5 discount coupon if you spend at
least $20. Solve an inequality that represents how much more you must spend to use the $5
coupon.
(1 Point)
Answer: The answer is m= ≥4.50
The required inequality is m ≥ 4.50
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, A shirt that you want to buy costs $15.50. You can use a $5 discount coupon if you spend at least $20.
Cost of the shirt = $15.50
you can use a $5 discount coupon if you spend at least $20
The question requires you to find how much more you need to spend to be able to use the $5 discount coupon
The shirt already cost $15.50
Total amount you need to spend = $20
Let the amount remaining = m
m ≥ $20 - 15.50
m ≥ $4.50
Hence, you need to spend $4.50 in order to be able to use the $5 discount coupon.

HELP ME PLEASE!! Find R and theta with the coordinates (-3,7).
Answer:
Since r is the distance from the origin to (x,y), it is the magnitude r=√x2+y2. Alternatively, from the equation (1), one can calculate directly that x2+y2=r2cos2θ+r2sin2θ=r2(cos2θ+sin2θ)=r2.

Solve for P
5/6p + 1= 3/4p -4
Answer: P= -60
Step-by-step explanation:
5/6p +1=3/4p -4
5/6p=3/4p-4. Subtract 1 from both sides
5p=9/2p-30. Trick( if there is a fraction multiply the denominator on both sides to make it a non fraction so life is easier, as I did I first multiply by 6)
10p=9p-60. multiply the second denominator on both sides(multiple by 2)
P=-60. Subtract 9p on both sides and keep the sign and you’ll get -60
2m:80cm.Give answer in lowest term PLEASE
Answer:
5:2
Step-by-step explanation:
In centimetres
convert 2 m to cm which will be 200 cm
then simplify 200 cm:80 cm --> 5:2
(we cancelled out the zero --> 20:8 then divide 20/2= 10 and 8/2= 4
again the same --> 10/2= 5 and 4/2= 2.
5 and 2 are prime numbers which have no other factor except for 1 and themselves so it cannot be simplified further.
Therefore your answer is 5:2
In metres
convert 80 cm to m which will be 0.8 m
the same steps: simplify 2:0.8
to remove the decimal move the decimal place one to the right --> 8
so you also have to move the decimal place to the right for the numerator: 20
20/8 = 5/2
