Question

find
the quadratic polynomial whose zerores are
are -4 and -5, is
​

Answer 1

Answer:

x square-x-12=0

Step-by-step explanation:

the quadratic polynomial is xsquare-x-12=0

Answer 2

Answer:

${x}^{2} + 9x + 20$

Step-by-step explanation:

sum of zeros= -4 + (-5)

= -4 -5

= -9

product of zeros = -4(-5)

= 20

so, our required quadratic polynomial is

${x}^{2} - (soz)x \: + (poz)$

${x}^{2} - ( - 9)x + (20)$

${x}^{2} + 9x + 20$
