Question

Find the roots of the quadratic equation x(1-x) – 2 = 0 by using factorisation method.

Answer 1

Answer:

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

$x - {x}^{2} - 2 = 0$

${x}^{2} - x + 2 = 0$

${x}^{2} - 2x + x - 2 = 0$

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

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

$x = 2 \: \: and \: \: 1$

Answer 2

Your question is wrong this question does not have any real roots.
