Question

3. Factorise.

(i) x2+xy+8x+8y

(ii) 15xy–6x+5y–2

(iii) ax+bx–ay–by

(iv) 15pq+15+9q+25p

(v) z–7+7xy–xyz​

Answer 1

Answer:

(i) x²+xy+8x+8y

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

= (x+8)(x+y)

(ii) 15xy−6x+5y−2

= 3x(5y−2) +1( 5y−2 )

=(3x+1)( 5y−2)

Answer 2

Answer:

Thanks for your question..

Your required answer :

• x² + xy + 8x + 8y
• x ( x + y ) + 8 ( x + y )
• ( x + 8 ) ( x + y )

• 15xy - 6x + 5y - 2
• 3x ( 5y - 2 ) + 1 ( 5y - 2 )
• ( 3x + 1 ) ( 5y - 2 )

• ax + bx - ay - by
• x ( a + b ) - y ( a + b )
• ( x - y ) ( a + b )

• 15pq + 15 + 9q + 25p
• 15pq + 9q + 15 + 25p
• 3q ( 5p + 3 ) + 5 ( 3 + 5p )
• ( 3q + 5 ) ( 5p + 3 )

• z – 7 + 7xy – xyz
• 1 ( z - 7 ) + xy ( z - 7 )
• ( 1 + xy ) ( z - 7 )
