4x2 + 12x + 8

To solve a quadratic equation, factorisation Method, formulae method or completing the square method can be used. But for the purpose of this question, the formulae method will be used.

(-b±√(b²-4ac))2a

Where a=4, b=12 and c=8

(-12±√(12²-4(4)(8))/2(4)

(-12±√(144-128)/8

(-12±√16)/8

(-12±4)/8

(-12+4)/8 or (-12-4)/8

-8/8 or -16/8
