Question

Factorise:
Y ^2-b^2 -8b-16
​

Answer 1

Answer:

${y}^{2} - 16 - {b}^{2} - 8b \\ {y}^{2} - {4}^{2} - ( {b }^{2} - {2 \sqrt{2} }^{2} ) \\ (y + 4)(y - 4) - (b + 2 \sqrt{2} )(b - 2 \sqrt{2} )$

Answer 2

Answer:

here is your answer

y^2 - b^2 - 8b - 16

(y)^2 -(b^2+8b+16)

(y)^2 - ( b+4)^2

formula used is a^2-b^2 = (a+b)(a-b)

(y+b+4)(y-b-4)

hope it helps u :)
