Find the zeros of the following quadratic polynomials ${x}^{2}+7x+10$ and verify the relationship between the zeros and the coefficients.

Karli Foley

$\therefore p\left(x\right)=0$
$⇒{x}^{2}+7x+10=0$
${x}^{2}+7x+10=0$
$⇒{x}^{2}+5x+2x+10=0$
$⇒$$x\left(x+5\right)+2\left(x+5\right)=0$
$⇒$$\left(x+5\right)\left(x+2\right)=0$
$⇒$$x=-5,-2$
