Question

Find the solutions of the system
y=x^2-2x-2
y=4x+5

Answer 1

start with
\[x^2-2x-2=4x+5\] then subtract \(4x\) and \(5\) to set it equal to zero
get
\[x^2-6x-7=0\]
fortunately this one factors so you don't have to use the quadratic formula to solve it

Answer 2

you get how to factor this?
