Sample Response: Both are correct. As long as inverse operations and the properties of equality are used properly, both methods will generate the same solution. They both isolate the variable on one side of the equation.
The line crosses the y axis
Add 13 to both sides
13 = 2x + 15x
Simplify right side
13 = 17x
Divide through by 17
13/17 = x
Hello,
if x≠-3
f(-3)=-2(-3)^3+(-3)²+16(-3)-15=-2*(-27)+9-48-15=54+9-48-15=0
f(x)/g(x)=(-2x^3+x²+16x-15)/(x+3)=(x+3)*(-2x²+7x-5)/(x+3)= -2x²+7x-5
