Answer:

-18

Step-by-step explanation:

Given:

f(x)=4-x^2 and g(x) =6x

h(3) = (g-f)(3)

= 6x - (4x^2)

= 6*3 -(4*3^2)

= 18 - 4*9

= -18

What is the factored form of 8x2 + 12x? 4(4x2 + 8x) 4x(2x + 3) 8x(x + 4) 8x(x2 + 4)
earnstyle [38]
So I'm guessing that the x2 is your way of saying 2 is the exponent right? In that case the equation would be 8x^2 + 12x
Well you would have to pull out the gcf which in this case will be 4x after pulling out the gcf you should get 4x(2x + 3)
