Question

Write a quadratic polynomial whose zeros are – 7 and +5.​

Answer 1

Step-by-step explanation:

Hence, the quadratic equation whose zeros are 7 and – 5 will be x2−2x−35=0.

Answer 2

Step-by-step explanation:

Given,

Sum of zeroes, α+β= -7

Product of zeroes,α×β= 5

.

. . The required quadratic polynomial

is p(x)=x²-(α+β)x + α×β

= x² - (-7)x + 5

= x²+7x+5
