Question

Can someone help guide me through this?
Solve the system:
y=x(squared)-3x-8
y=x+4

Answer 1

you can show x squared like this: x^2

Answer 2

Oh ok thanks I'll remember that

Answer 3

y = x^2-3x-8--------(1)

y= x+4 ---------(2)

(2) = (1) [ two equations right hand sides are equal]

x^2-3x-8 = x+4 [ L. H.S ARE EQUAL]

SOLVE FOR x

Answer 4

Ok I combined them and got
x^2-4x-12=0

What method should I use to solve for x

Answer 5

You can factor that (if you know how)
