Question

Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients 1)x²-7 2)3x²-9x 3) x²-x-90 please solve it fast

Answer 1

1. by using a sqaure - b sqaure identity

x= -root7 or x eqauls plus root 7

lets the zeroes be A and B

A+B = -b/a

ie -(-7)/1 = 7

A×B= c/a ie 0/1 =0

hence verified

2.follow the same like first

3.follow the same method like first

you will get it

Answer 2

$ANSWER$

plzz refers the attachment

For second one follow the same method!!
