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