10 x -1 = -10
2x + 1 =
^2
its super easy just factorize all the quotations
2x + 1 =
^2
its super easy just factorize all the quotations
10x-1 = (2x + 1)^2
10x-1= 4x^2 + 4x + 1
subtract 4x^2 + 4x + 1 from both sides
-4x^2 + 6x - 2 = 0
-2(2x-1)(x-1) = 0
2x-1=0; x-1=0
x=1/2 x=1
10x-1= 4x^2 + 4x + 1
subtract 4x^2 + 4x + 1 from both sides
-4x^2 + 6x - 2 = 0
-2(2x-1)(x-1) = 0
2x-1=0; x-1=0
x=1/2 x=1
