Question

factorise y2+ 24y+144

Answer 1

y^2 + 24y + 144

use identiy :

a^2 + 2ab + b^2 = ( a + b)^2

=(y)^2 + 2 ( y )( 12 ) + ( 12 )^2

=(y + 12 )^2

=(y + 12 ) (y + 12 )

Answer 2

Answer:

On comparing with standard quadratic equation that is ax2 + bx + c.

Let us simplify the given expression, we get

y2 + 24y + 144 = y² + 12y + 12y + 144

= y(y + 12) + 12(y + 12)

= (y + 12) (y + 12)
