Question

Multiply. x^2 + 8x + 15/x-4 x x^2-16/2x+6

Answer 1

= 1/2 ( x + 5 ) ( x + 4 )

Answer 2

To find the answer for this question:

x^2 + 8x 15/x - 4xx^2 - 16/2x + 6

Apply the exponent rule:
x^2 + 8x + 15/x - 4x^3 - 16/2x + 6

Divide the numbers: 16/2 = 8:
x^2 + 8x + 15/x - 4x^3 - 8/x + 6

Apply the rule: a/c +/- b/c = a +/- b/c
x^2 + 8x + 15-8/x - 4x^3 + 6

After you subtract the numbers: 15 - 8 from the fraction that equals to 7:
x^2 + 8x + 7/x - 4x^3 + 6

So, your answer would be: x^2 + 8x + 7/x - 4x^3 + 6.
