Question

factotise 4x²-4x-1 help me​

Answer 1

4x^2 - 8x + 4 = 0

4x^2 - 8x + 4 = 0dividing entire equation by 4,

4x^2 - 8x + 4 = 0dividing entire equation by 4,x^2 - 2x + 1 = 0

4x^2 - 8x + 4 = 0dividing entire equation by 4,x^2 - 2x + 1 = 0now splitting the middle term,

4x^2 - 8x + 4 = 0dividing entire equation by 4,x^2 - 2x + 1 = 0now splitting the middle term,x^2 - x - x + 1 = 0

4x^2 - 8x + 4 = 0dividing entire equation by 4,x^2 - 2x + 1 = 0now splitting the middle term,x^2 - x - x + 1 = 0means, (x)*(x) - X - X + 1 = 0

4x^2 - 8x + 4 = 0dividing entire equation by 4,x^2 - 2x + 1 = 0now splitting the middle term,x^2 - x - x + 1 = 0means, (x)*(x) - X - X + 1 = 0now taking common,

4x^2 - 8x + 4 = 0dividing entire equation by 4,x^2 - 2x + 1 = 0now splitting the middle term,x^2 - x - x + 1 = 0means, (x)*(x) - X - X + 1 = 0now taking common,x(x-1) - 1(x-1) = 0

4x^2 - 8x + 4 = 0dividing entire equation by 4,x^2 - 2x + 1 = 0now splitting the middle term,x^2 - x - x + 1 = 0means, (x)*(x) - X - X + 1 = 0now taking common,x(x-1) - 1(x-1) = 0now taking common from this,

4x^2 - 8x + 4 = 0dividing entire equation by 4,x^2 - 2x + 1 = 0now splitting the middle term,x^2 - x - x + 1 = 0means, (x)*(x) - X - X + 1 = 0now taking common,x(x-1) - 1(x-1) = 0now taking common from this,(x-1)*(x-1)=0

4x^2 - 8x + 4 = 0dividing entire equation by 4,x^2 - 2x + 1 = 0now splitting the middle term,x^2 - x - x + 1 = 0means, (x)*(x) - X - X + 1 = 0now taking common,x(x-1) - 1(x-1) = 0now taking common from this,(x-1)*(x-1)=0(x-1)^2 is your answer
