Question

What is the solution to the following system of equations?
y = x2 + 10x + 11
y = x2 + x − 7

Answer 1

I would use the fact that both equations have their left sides equal,
\[x^2 + 10x + 11=x^2 + x − 7\] Solve for x.

Answer 2

9x+X^2

Answer 3

9x^4

Answer 4

You should group the powers with the same exponent,
\[x^2+10x+11-x^2-x+7=0\Rightarrow9x+18=0\Rightarrow 9x=-18\] And solve for x.

Answer 5

i dont kind of get it to many number it kinda confused
