Question

Find the zeroes of the quadratic polynomial x2 + 8x + 16 and verify the relationship between the zeroes and the coefficients.

Answer 1

Answer:

X square + 8 x + 16

X square + 4 x + 4 x + 16

X bracket X + 4 bracket close + 4 bracket + 4 bracket close

X + 4 is equal to zero

x is equal to minus 4 in both of the cases

sum is equal to alpha + beta is equal to minus b Upon A

is equal to minus 4 + bracket - 4 bracket close is equalto 8

is equal to 8 is equal to 8

Alpha into beta is equal to C Upon A

minus 4 into minus 4 is equal to 16

16 is equal to 16
