0FACTORISE THE FOLLOWING:
TYPE 1:-
a2-b2 =(a+b)(a-b)
Ex:-
1) x2-64 =x2-82
=(x+8)(x-8)
TYPE 2:- splitting the middle term
Method:-
split the middle term in two terms so that-
1)Their alzebric sum should be equal to middle term and
2)Their product should be equal to product of 1st and 3rd term.
3)Make the group of twq terms each
4)Remove out the common in each group.
Ex:-
x2-10x+24
=x2-6x-4x+24
=x(x-6)-4(x-6)
=(x-6)(x-4)
