Question

the pair of zeros of the polynomial 2x square + 14 x + 20 is equal to​

Answer 1

$\textbf{Given:}$

$\textsf{Polynomial is}\;\mathsf{2x^2+14x+20}$

$\textbf{To find:}$

$\textsf{Zeros of the polynomial}$

$\textbf{Solution:}$

$\mathsf{2x^2+14x+20}$

$\mathsf{=2(x^2+7x+10)}$

$\mathsf{=2(x^2+5x+2x+10)}$

$\mathsf{=2(x(x+5)+2(x+5))}$

$\mathsf{=2(x+2)(x+5)}$

$\mathsf{Now,}$

$\mathsf{2x^2+14x+20=0}$

$\mathsf{2(x+2)(x+5)=0}$

$\mathsf{2(x+2)(x+5)=0}$

$\mathsf{(x+2)(x+5)=0}$

$\mathsf{x+2=0\;\;or\;\;x+5=0}$

$\mathsf{x=-2\;\;or\;\;x=-5}$

$\therefore\textsf{The zeros of the polynomial are -2, -5}$
