Question

factorise -4x^2+4x-1 please answer fastly​

Answer 1

Answer:

$\large{\pink{\boxed{x = \frac{1}{2}\:\&\: x = \frac{-1}{2}}}}$

Step-by-step explanation:

-4x² + 4x - 1 = 0

-4x² + 2x + 2x - 1 = 0

-2x(2x - 1) + 1(2x - 1) = 0

(2x - 1)(-2x + 1) = 0

$\large{\pink{\boxed{x = \frac{1}{2}\:\&\: x = \frac{-1}{2}}}}$

Answer 2

Answer:

x=1/2

Step-by-step explanation:

-4x²+4x-1

=-[(2x)²-2.2x.1+1²]=0

(2x-1)²=0

x=1/2
