What is Polynomial?A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.
Given a trinomial equation:
f(x)=x^3+kx-4
And also given it has a factor (x - 1)
Thus, at x = 1 the value of the f(x) will be 0
So,
f(x) = x^3 + kx - 4
f(1) = 1^3 + k*1 - 4
0 = 1 + k -4
k = 3
therefore, The value of k = 1 for the given Trinomial that has the factor (x -1)

Answer: (x-3)(x-1)(x+5)
Step-by-step explanation: Factor this polynomial, to do that you use the rational roots theorem.
Answer: (x-1)(x-3)(x+5)
Step-by-step explanation:
Use the rational root theorem
Constant term = 15, Coefficient of leading term = 1
Factors of 15: 1, 3 , 5, 15
Factors of 1: 1
Therefore, (x-1) is a factor

Value of an algebraic expression depends on the values of its variables usually. The value of [tex]2x^2[/tex] for given condition is obtained to be 18
How to evaluate a given mathematical expression with variables if values of the variables are known?You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.
For the given case, we are given that [tex]x - 1 =2[/tex]
By this, we can get the value of the variable 'x' as:
[tex]x - 1 = 2\\\text{Adding 1 on both the sides, we get}\\x = 3[/tex]
Now, putting 3, in place of x, in expression [tex]2x^2[/tex], we get:
[tex]2x^2 = 2 \times (3^2) = 2 \times 9 = 18\\[/tex]
( sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together, thus, [tex]2x^2 = 2 \times x^2[/tex])
Thus, the value of [tex]2x^2[/tex] for given condition is obtained to be 18

Triangle PQR has angles in the ratio of 2:3:5.
Which type of triangle is APOR?
1) acute
2) isosceles
3) obtuse
4) right
What is the answer???
Answers
Answer:(4) right angle
Step-by-step explanation:
you need to get 180 right solve it from there
The angle is 90degrees, hence the triangle PQR is right triangle
The sum of an interior angle of a triangle is 180 degrees. If the triangle PQR has angles in the ratio of 2:3:5.
Sum of the ratio = 2 + 3 + 5
Sum of the ratios = 10
For the ratio of m<P:
<P = 2/10 * 180
<P = 36 degrees
For the angle m<Q
m<Q = 3/10 * 180
m<Q = 54 degrees
For the angle R;
m<R = 5/10 * 180
m<R = 90 degrees
Since one of the angles is 90degrees, hence the triangle PQR is right triangle

please solve this equation and show work please tysm 3(g−7)=2(10+g)
Answers
Answer:
g=41
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(g−7)=2(10+g)
(3)(g)+(3)(−7)=(2)(10)+(2)(g)(Distribute)
3g+−21=20+2g
3g−21=2g+20
Step 2: Subtract 2g from both sides.
3g−21−2g=2g+20−2g
g−21=20
Step 3: Add 21 to both sides.
g−21+21=20+21
41
Step-by-step explanation:
3(g-7)=2(10+g)
3g-21=20+2g
3g-2g=20+21
g=41
