Answer: $x^2+2x+1=36$

Step-by-step explanation:

$x^2+2x-35=0$

add 35 on both sides.

$x^2+2x-35+35=0+35$

$x^2+2x=35$

take the value of b (2) divide it by 2 and square it.

$x^2+2x+(\frac{b}{2})^2 =35+(\frac{b}{2})^2$

$x^2+2x+(\frac{2}{2})^2 =35+(\frac{2}{2})^2$

$x^2+2x+(1)^2=35+(1)^2\\x^2+2x+1=35+1\\x^2+2x+1=36$

F(x) = x°-9x

laila [671]

F(x)=x^3-9x
and
g(x)=x^2-2x-3

so you just need to divide f(x) by g(x)

Therefore:

f(x)/g(x) = (x^3-9x) / (x^2-2x-3)

and of course you need to factor these two function to see if some factor would cancel another

x^3-9x = x(x^2-9)=x(x-3)(x+3)
and
x^2-2x-3 = (x-3)(x+1)
