Answer: -3(x^2 + 1)(x-5)
Explanation: -3x^3 + 15x+3x -15
Factor by grouping: -3x^2(x-5) +3(x-5)
Combine: (-3x^2 +3)(x-5)
Factor by GCF: -3(x^2 +1)(x-5)
Set equal to zero: (x^2 +1)=0
(x+5)=0
Solve: x=5, x=square root of 1
Answer: tis C
Step-by-step explanation:
x^2/x^2*z^2/y^-2
=1*z^2/y^-2
=z^2y^2
=y^2z^2
