Question

The zeors of the quadratic polynomial x² +7x +10 are

Answer 1

Answer:

The zeroes of the quadratic polynomial is -2 and -5

Step-by-step explanation:

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

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

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

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

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

either, x+2=0 , x= -2

or, x+5=0 , x= -5
