Which product of prime polynomials is equivalent to 8x4 + 36x3 – 72x2?
4x(2x – 3)(x2 + 6)
4x2(2x – 3)(x + 6)
2x(2x – 3)(2x2 + 6)
2x(2x + 3)(x2 – 6)

Second option is correct.

Step-by-step explanation:

Since we have given that

We need to solve the polynomials into product of prime polynomials :

1) Taking common factor i.e. 4x

2) Now, we will split the middle term of quadratic equation:

3) Now, combine all the expression :

Hence, Second option is correct.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

definitely a. the others have almost all data points on one side of the line.
