Question

find the zeroes of the quadratic polynomial x^2+8x+15 and verify the relationship between the zeroes and the coefficient​

Answer 1

Answer:

x

2

−8x+15

=x

2

−5x−3x+15

=x(x−5)−3(x−5)

=(x−5)(x−3)

∴ the zeroes of the polynomial are 5 and 3 where both are positive.

Step-by-step explanation:

x

−5x−3x+15

=x(x−5)−3(x−5)

=(x−5)(x−3)

∴ the zeroes of the polynomial are 5 and 3 where both are positive.
