Question

a- y² + 2y + xy + 2x
b- 10ab + 5a + 2b + 1
c- pqr - 3pq + r² - 3r
d- ap² + bp² + bq² + aq²
e- xy + x + y + 1
f- x( x+ y) - 10x - 10y
please answer ​them ​

Answer 1

Answer:

a) by grouping we will do the first part

= y(y+2) + x(y+2)

= (y+2) (y+ x)

b ) here also we will do the grouping

= 5a(2b+ 5) + 1 ( 2b+ 1)

= (5a+1) ( 2b+5)

c) here also we will do by grouping it

= pq(r - 3) + r ( r - 3)

= (pq+r) ( r-3)

d) by grouping this question will be done

= p²( a+ b) + q²( b+ a)

= (p²+q²) ( b+a)

e) here also we will do grouping

= x(1+y) + 1 ( y+1)

= (x+1) ( y+ 1)

f) first we will multiply it

= x²+ xy -10x-10y

now , we will do grouping

= x( x+ y) -10( x + y )

= (x+y) ( x-10)
