The square of 4x-6x-3 = 0

The square of 4x-6x-3 = 0


The square of 4x-6x-3 = 0
The square of X - 3x / 2-3 / 4 = 0
Square of (x-3 / 4) - 3 / 4 = 0
Square of (x-3 / 4) - 21 / 16 = 0
Square of (x-3 / 4) = 21 / 16
X-3 / 4 = (radical 21) / 4, or x-3 / 4 = (radical 21) / 4
X = 3 / 4 + (radical 21) / 4, or x = 3 / 4 - (radical 21) / 4



X2 + 4x-5 = 0 (matching method)


The formula is x2 + 4x + 4 = 5 + 4, that is, (x + 2) 2 = 9, the prescription is x + 2 = ± 3, then X1 = 1, X2 = - 5



4x squared-x-5 = 0 with matching method


(4x-5)(x+1)
