Question

the two zeroes of a quadratic polynomial are -4 and -6. find the sum and product of the zeroes. what is the value of coefficient b?

Answer 1

Sum of zeroes = -10

Product of zeroes = 24

Thus the quadratic polynomial so formed will be

x^2 + 10x + 24

So the coefficient of b is 10

Answer 2

Step-by-step explanation:

answer is -7

Step-by-step explanation:

X²+7x+10=0

x²+2x+5x+10=0

x(x+2)+5(x+2)=0

(x+2)(x+5) = 0

x+2 = 0 ; x = -2

x+5 = 0 ; x = -5

∝= -2  β = -5

Sum of zeroes = -2+(-5) = -2-5 

= -7/1 = -b/a = -7
