Question

factorise 20 x square - 26 X + 8

Answer 1

$20 {x}^{2} - 26x + 8 \\ 20 {x}^{2} - 10x - 16x + 8 \\ 10x(2x - 1) - 8(2x - 1) \\ (10x - 8) \times (2x - 1)$

Answer 2

divide by 2
10xsquare -13x+4
now in multiply two number which result=40
and whose sum is -13
sooo
these are -5 and -8
(x-5)(x-8)
sooo
X=5 AND X=8
