Answer:
here u go
Step-by-step explanation:
−9x3−72x2−96x+36=3x3+x2−3x+8
Step 1: Subtract 3x^3+x^2-3x+8 from both sides.
−9x3−72x2−96x+36−(3x3+x2−3x+8)=3x3+x2−3x+8−(3x3+x2−3x+8)
−12x3−73x2−93x+28=0
Step 2: Factor left side of equation.
(−4x+1)(x+4)(3x+7)=0
Step 3: Set factors equal to 0.
−4x+1=0 or x+4=0 or 3x+7=0x=14 or x=−4 or x=−73
Answer:
x=14 or x=−4 or x=−73
