Answer:
[tex]x^2 -5x-14=0[/tex]
Step-by-step explanation:
[tex]\text{Given that, the roots are}~ \alpha = -2~ \text{and}~ \beta = 7.\\\\\text{The quadratic equation with roots}~ \alpha~ \text{and}~ \beta ~ \text{is,} \\\\~~~~~~~x^2 - \left(\alpha + \beta \right)x + \alpha \beta =0 \\\\\implies x^2 -(-2+7)x + (-2)(7) = 0\\\\\implies x^2 -5x-14=0[/tex]
Answer:
Step-by-step explanation:
the quadratic equation is:
(x + 2)(x - 7)= 0
x^2 - 7x + 2x - 14
x^2 - 5x - 14
y = x^2 - 5x - 14
