Question

the sum of zeros of polynomials x square+7x+10 is -7​

Answer 1

Step-by-step explanation:

-7 is the sum of zeros please do follow me

Answer 2

Answer:

${x}^{2} + 7x + 10$

$= {x}^{2} + 2x + 5x + 10$

$= x(x + 2) + 5(x + 2)$

$=( x + 2)(x + 5)$

ZEROES :–

$x + 2 = 0 \\ x = - 2$

$x + 5 = 0 \\ x = - 5$

SUM OF ZEROES :–

$- 2 - 5 = - 7$

Hence proved that sum of zeroes of polynomial ${x}^{2} + 7x + 10$ is $- 7</strong><strong>.</strong><strong>$
