Question

2 , -2 verify the relationship between the coefficients and zeroes class 10​

Answer 1

x² -4 = 0

here a = 1, b = 0,c = -4

x² = 4

therefore,the roots of given equation are

±2.

as we now that ,

sum of roots = -b/a

-2 +2 =0/1

0 = 0

L.H.S = R.H.S

product of roots = c/a

-2 × 2 = -4/1

-4 = -4

L.H.S = R.H.S
