Question

Hey friends, please do answer this question
__
FACTORISE :

$x { }^{2} - 17x + 16 \\ y {}^{2} - 21y + 90$
PLEASE ANSWER IT FAST!!!!!!!!!!!

Answer 1

x square -16x - 1x + 16
x (x-16) - 1 (x-16)
(x-1) (x-16)

y square -15y - 6y + 90
y (y-15) - 6 (y-15)
(y-6) (y-15)

Answer 2

$<b><huge>Answer:-)<b><huge>$


x²-17x+16

x²-16x-x+16

x(x-16)-1(x-16)

(x-1)(x-16


======================================


Y²-21y+90

y²-15y-6y+90

y(y-15)-6(y-15)

(y-15)(y-6)

°================================°


Thanks!!!!
