Dear Student,

You forgot to give the options. But don't worry, I'll answer all ur doubts.

# Methods of solving a quadratic equation -

the quadratic formula

completing the square

factoring

using the square roots

◆ Answer -

x = -1 + √5/2√2

x = -1 - √5/2√2

● Explanation -

Comparing with standard quadratic equation ax²+bx+c = 0,

a = 8

b = 16

c = 3

Using quadratic formula -

x = [-b±√(b²-4ac)] / 2a

x = [-16±√(16²-4×8×3)] / 2×8

x = [-16±√(256-96)] / 16

x = (-16±√160) / 16

x = (-16±4√10) / 16

x = (-4±√10) / 4

x = -1 ± √5/2√2

So two solutions are -

x = -1 + √5/2√2

x = -1 - √5/2√2
