Question

The 2 zeroes of a quadratic polynomial are -4 and -6. Find the sum and product of zeroes . What is the value of coefficient B

Answer 1

Sum of zeros = (-4) + (-6) = - 10

Product of zeros = (-4) × (-6) = 24

And the coefficient B = 10

Because sum of zeros = - B/A = - 10/1

Therefore B = 10
