Question

If alpha and beta are the zeroes of the polynomial then find alpha square minus beta square. P(x)= 2x2 +5x _ 9

Answer 1

Answer:

firstly equation is wrong .

the correct equation is 4x^2+5x-9

if alpha and beta is the zeroes then ,

alpha + beta =-b/ a

alpha.beta = c/a

=) -5 /4

=) 9/4

alpha^2 - beta ^2= (alpha+ beta) ^2 +2alpha beta

(-5/4)^2+ 2×9/4

solve it

the answer u will get is 47/16

hope it help you

please mark it as brainliest answer
