Question

y2 + 24y + 144 factorise
​

Answer 1

Answer:

${y}^{2} + 12y + 12y + 144 \\ \\ y(y + 12) + 12(y + 12) \\ \\ (y + 12) \times (y + 12)$

Answer 2

Answer:

Hey mate...

Good evening..♥

Rewrite 144 as 12 square

Y square + 24 Y + 12 square

Check the middle term by multiplying 2xy and compare this result with the middle term in original expression...

2ab = 2.y.12

Simplify 2ab= 24 y

Factorise using the perfect identity

$x {}^{2} + 2xy + y {}^{2}$

Gives (x+y).2

Therefore,your answer is (y+12).2
