Question

Reduza as equações abaixo a sua forma normal e resolva (2x 1)ao quadrado = (3x-1).(5x-1)

Answer 1

(2x+1)²=(3x-1).(5x-1)
2x²+2.2x.1+1²=15x²-3x-5x+1
4x²+4x+1=15x²-8x+1
4x²-15x²+4x+8x+1-1
-11x²+12x=0
-11x(x+12)=0
-11x=0.(-1)
11x=0
x=0/11
x=0
x+12=0
x=0-12
x=-12
(2x-1)²=(3x-1).(5x-1)
2x²-2.2x.1+1²=15x²-3x-5x+1
4x²-4x+1=15x²-8x+1
4x²-15x²-4x+8x+1-1
-11x²+4x=0
-11x(x+4)=0
-11x=0.(-1)
11x=0
x=0/11
x=0
x+4=0
x=0-4
x=-4
