Q. 5 E5.0( 5 Votes )

Solve the following equations using the general formula:

3x2 + 5√2x + 2 = 0

Answer :

Comparing equation 3x2 + 5√2x + 2 = 0 with ax2 + bx + c = 0 we get


a = 3, b = 5√2 and c = 2


Discriminant (D) = b2 – 4ac


D = (5√2)2 – 4(3)(2)


D = (52)(√2)2 – 4 × 6


D = 25 × 2 – 24


D = 50 – 24


D = 26


D > 0 implies roots are real and distinct and given by







Therefore and
