area of rectangle is x2+7x+10
formula:-
area of rectrangle= l × b
we can use splitting the middle term method for more easily understand.
so,
=x2+7x +10
=x2+2x+5x+10
=x (x+2)+5 (x+2)
=(x+2)(x+5)
therefore,
l=x+2
and
b=x+5

so,
=x2+7x +10
=x2+2x+5x+10
=x (x+2)+5 (x+2)
=(x+2)(x+5)
therefore,
l=x+2
and
b=x+5

x²+7x+10
x²+5x+2x+10
x(x+5)+2(x+5)
(x+5)(x+2)=Length×Breadth
l=(x+5),b=x+2
x²+5x+2x+10
x(x+5)+2(x+5)
(x+5)(x+2)=Length×Breadth
l=(x+5),b=x+2
