PLEASE HELP I REALLY DONT UNDERSTAND IT :( WILL MARK BRAINLIEST FOR CORRECT AND IN-DEPTH ANSWERS :)
Solve the following Quadratic Equations, then sketch.
Steps
1) set y=0 (This ensures our x's will be x-intercepts)
2) Factor the Quadratic Equation into 2 parentheses, ( )( )
3) Interpret factors to get x-intercepts
4) Sketch the parabola

1) y=x^2+2x-15 2) y=x^2+5x+6

3)y=x^2-6x-40 4) y=x^2-8x+12
