Question

Factorise :
1.
${x}^{2} + xy + 8x + 8y$
2.
$15xy - 6x + 5y - 2$
​

Answer 1

Answer:

1. x²+xy+8x+8y

x(x+y) +8(x+y)

(x+8) (x+y)

2. 15xy-6x+5y-2

3x(5y-2) +1(5y-2)

(3x+1) (5y-2)

I hope my answer helps you ☺☺

Answer 2

Answer:

1]. x² + xy + 8x + 8y

= x( x + y ) + 8 ( x + y )

= ( x + 8 ) ( x + y )

2]. 15xy−6x+5y−2

=15xy+5y−6x−2

=5y(3x+1)−2(3x+1)

=(3x+1)(5y−2)
