-2x + 6 -
-13x - 16
= -15 + 22

or
(-2x+6)-(13x-16)
= -2x+6-13x+16
= -15x+22
= 22- 15x

I need help PLEASE I have to factor the examples and I also need to show my steps I forgot how to do it can somebody plz help!!

Zina [86]

For this, all you need to do is factor out the GCF, or greatest common factor. To find the GCF of these terms, list the factors of each term and the greatest one they share is their GCF. In this case, the GCF is 5x. <u>Factor out 5x from this expression, and your answer is going to be $5x(2x-5)$ </u>

If f(x) = 2x2 - x - 6 and g(x) = x2 - 4, find f(x) ÷ g(x).

Phantasy [73]

$f(x)=2x^2-x-6,\ g(x)=x^2-4\\\\f(x)\div g(x)=\dfrac{f(x)}{g(x)}=\dfrac{2x^2-x-6}{x^2-4}=\dfrac{2x^2-4x+3x-6}{x^2-2^2}\\\\=\dfrac{2x(x-2)+3(x-2)}{(x-2)(x+2)}=\dfrac{(x-2)(2x+3)}{(x-2)(x+2)}=\dfrac{2x+3}{x+2}\ for\ x\neq0\\\\Answer:\ f(x)\div g(x)=\dfrac{2x+3}{x+2}$
