Question

solve system y=-3x^2+x+4
y=-2x-2

Answer 1

If they both equal y that means they equal each other. So you can get x with:
\[-3x^2 + x + 4 = -2x - 2\]

Answer 2

work?

Answer 3

-3x^2+x+4=-2x-2
-3x^2+4=-3x-2
-3x^2=-3x-6
-3x^2+3x+6=0
(-3x+6)(x-3)=0
-3x+6= 0 x-3=0
-3x=-6 x=3
x=-6/-3=6/3
x=2
