Question

factories y^2-10y+25​

Answer 1

Answer:

y2-5y-5y+25

y(y-5)-5(y-5)

(y-5)(y-5)

Answer 2

Step-by-step explanation:

y²-10y+25

We have two ways to factorise it.the first way is through middle term splitting

y²-10y+25

=y²-5y-5y+25

=y(y-5)-5(y-5)

=(y-5)(y-5)

=(y-5)²

OR we can solve it through algebraic identity i.e. a²-2ab+b²=(a-b)²

y²-10y+25

=(y)²-2×y×5+(5)²

=(y-5)²
