Question

if the zeros of the quadratic polynomial X*2+(a+1)x+are 2 and -3then​

Answer 1

Answer:

Given

Quadratic polynomial is x² + (a+1)x + b

zeroes of the polynomial are 2 and -3

sum of the zeroes = \frac{a+1}{1}

1

a+1

= 2-3

a+1 = -1

a = -2

product of the zeroes = \frac{b}{1}

1

b

= 2(-3)

b = -6
