Question

How can I Solve this ??

Find the values of x for which f(x)=g(x)

1.) f(x)= x^2 + 3x + 4 , G(x)= 5x + 28


PLS. HELP ME :))))))) and show the solution :)

Answer 1

I'm assuming g(x) and G(x) are the same thing here?

If so, then

x^2+3x+4=5x+28
x^2-2x-24=0
(x-6)(x+4)=0
x=6, x=-4

You can now plug them back in and check.

Answer 2

Thank You :D

Answer 3

How come that x +4 became x= -4 ?? and x-6 became x=6 ??
