Question

what is meaning of factorisation of expressions ?give one example to explain

Answer 1

Heya..

________________

Factorisation of expressions means to find factors of expressions.

Like : (5x^2 + 20x) :

Then firstly we have to check common terms between both..

As 5x is common.

= 5x(x+4).

Other questions are slove same as above.

But it uses many formulas like:

(a+b) ^2 = a^2 + 2ab + b^2

(a-b) ^2 = a^2 - 2ab + b^2

a^2 - b^2 = (a+b) (a-b)

And many more..

Hope it's helpful to u.
