Question

how to do this sum hurry tomorrow exam​

Answer 1

Answer:

it's easy

first you need to split the middle term

and then ur answer is ready..

let me show you..

${y}^{2} - 5y + 6$

when we split the middle term we should get 6 when we multiply any two no. and when we add those two no. we should get -5

So..

${y}^{2} - 2y - 3y + 6$

take common and ur answer is.

$y(y - 2) - 3(y - 2)$

I. e

$y - 2 \: and \: y - 3$

then ur answer is Y=2 or Y=3

HOPE IT HELPS YOU

Answer 2

= y² - 5y + 6

= y² - 2Y - 3y + 6

= Y(Y - 2) - 3(Y -2)

= $\huge\boxed{(Y - 2)(Y - 3)}$
