Question

factorise step by step:- y²-8y+16​

Answer 1

Step-by-step explanation:

Method 1

y²-8y+16

= y²-4y - 4y +16

= y(y-4) - 4(y-4)

= (y-4)²

Method 2

y²-8y+16

=(y)² - 2.y.4 + 4²

= (y-4)²

Answer 2

Answer:

y^2-8y+16

y^2-4y-4y+16

y(y-4)-4(y-4)

(y-4)(y-4)

(y-4)^2. (answer finished)

Y^2+16-8y after factorising the answer came same
