Question

The quadratic polynomial P(y) with -15 and -7 as sum and one of the zeroes respectively.

a. y2+15y+56

b. b. y2-15y-56

c. c. y2+15-56

d. d. Non of these.

​

Answer 1

Answer:

d. None of the above

Step-by-step explanation:

Given,

Sum of zeroes = -15

one of the zeroes = -7

If one of them is -7, then the other is (-15+7) = -8

polynomial, p(y) = $y^2 +(a+b)y +ab$

${y}^{2} + ( - 15 )y + ( - 8)( - 7)$

${y}^{2} - 15y + 56$

So, ur answer is 'd'
