# Solve the following equations using the general formula:3x2 + 5√2x + 2 = 0

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
