Question

Find the factor: x²-4x+5=0

Answer 1

${x}^{2} - 4x - 5 = 0 \\ \\ {x}^{2} - 5x + x - 5 = 0 \\ \\ x(x - 5) + 1(x - 5) \\ \\ (x + 1)(x - 5) \\ \\ x = - 1 \: or \: x = 5 \\ \\ mark \: me \: as \: brainliest$

Answer 2

Answer:

$= > x ^{2} - 4x + 5 = 0 \\ \\ = > x = \frac{ - ( - 4) \: \pm \: ( - 4) ^{2} - 4 \times 1 \times 5 }{2} \\ \\ = >x = \frac{4 \pm \: 16 - 20}{2} \\ \\ = > x = \frac{4 \: \pm \: - 4}{2} \\ \\ = > x = either \: 0 \: or \: 4$
