Question

How to factorize splitting the middle term

Answer 1

We should better take an example here.. Right??

Answer 2

yup

Answer 3

go ahead

Answer 4

explain me with an example please

Answer 5

So, let us factor firstly a simple one..

\(Example : Factorize \; \; \; x^2 + 4x + 3\)

Answer 6

Firstly you must compare it with standard equation given as: \(ax^2 + bx + c\)

Can you tell me on comparison, what are values of a,b and c?

Answer 7

say WHAT

Answer 8

yup @waterineyes

Answer 9

first of all we w'll take lcm of by multiplying 3 to \(x^2\)
now, by taking lcm we get \(3*1\) so

in middle we add those numbers which ...if we add them then we get 4x

Answer 10

okay

Answer 11

here we add \(x\) instead of co-efficient ''1''
now \(x^2+3x+x+3\)
OK

Answer 12

now we we'll make factors by taking common
\(x{(x+3})~+~1(x+3)\)

\((x+1)(x+3)\) this is answer
