Answer:
{Given quadratic polynomial x2 + 7x + 10}
Using factorisation (splitting the middle term)
x2 + 7x + 10 = 0
x2 + (5x + 2x) + 10 = 0
x2 + 5x + 2x + 10 = 0
x(x + 5) + 2 (x + 5) = 0
(x + 5) (x + 2) = 0
Hence, zeroes of a given quadratic polynomial are – 5 and – 2.
Sum of zeroes = -2+(-5) = -2-5
= -7/1 = -x coefficient /x² coefficient
Product of zeroes = (-2)(-5)
= 10/1 = constant/x² coefficient.
