Q2 of 83 Page 76

Verify whether the given value of x is a solution of the quadratic equation or not:

(3x — 8)(2x + 5) = 0, x = –

will be solution of quadratic equation (3x — 8)(2x + 5) = 0 if satisfies the given equation


put in L.H.S of (3x — 8)(2x + 5) = 0


⇒ L.H.S


⇒ L.H.S ]


⇒ L.H.S


⇒ L.H.S = 0


⇒ L.H.S = R.H.S


Thus satisfies the equation (3x — 8)(2x + 5) = 0 hence is a solution
