Verify whether the given value of x is a solution of the quadratic equation or not:
x² + x — 2 = 0, x = 2

Question

Verify whether the given value of x is a solution of the quadratic equation or not:x2 + x — 2 = 0, x = 2

Philoid · Accepted Answer

x = 2 will be solution of quadratic equation x² + x — 2 = 0 if x = 2 satisfies the given equation

put x = 2 in L.H.S of x² + x — 2 = 0

⇒ L.H.S = 2² – 2 + 2

⇒ L.H.S = 4

⇒ L.H.S ≠ R.H.S

Thus x = 2 does not satisfies the equation x² + x — 2 = 0 hence x = 2 is not a solution
