Question

(2x+1)2=(x-1)2+3x(x+2)

ayuda plis con esta ecuación :(​

Answer 1

Respuesta:

(2x+3)/(2x-4) = (x-1)/(x+1)

(2x+3)(x+1) = (x-1)(2x-4)

2x(x+1)+3(x+1) = x(2x-4)-1(2x-4)

2x²+2x+3x+3 = 2x²-4x-2x-(-4)

2x²+(2+3)x+3 = 2x²-(4+2)x+4

2x²+5x+3 = 2x²-6x+4

2x²+5x+3-2x² = 2x²-5x+4-2x²

5x+3 = -6x+4

5x+3+6x = -6x+4+6x

(5+6)x+3 = 4

11x+3 = 4

11x+3-3 = 4-3

11x = 1

11x/11 = 1/11

x = 1/11
