X^2+4X+3

Plz do fast.​

Answer 1

Answer:

$\huge{\underline{\underline{\tt{\blue{Question}}}}}$

Factorise x²+4x+3

$\huge{\underline{\underline{\tt{\blue{To\ Do\: Factorise}}}}}$

$\fbox{\LARGE{\underline{\underline{\pink{\bf{Solution}}}}}}$

Step-by-step explanation:

x²+4x+3

x²+x+3x+3

x(x+1)+3(x+1)

(x+3)(x+1)

$\large{\bold{\underline{\underline{\pink{\bf{req}\green{uir}\red{ed}\:\orange{ans}\blue{wer}}}}}}$

Hence,

Answer (x+3)(x+1)

$\fbox{\LARGE{\underline{\underline{\blue{\bf{MORE TO KNOW}}}}}}$

In Mathematics, factorisation is defined as the breaking or decomposition of an entity.

(for example a number, a matrix, or a polynomial) into a product of another entity, or factors, which when multiplied together give the original number or a matrix, etc.

Answer 2

$\huge\bf\orange{answer:}$

$\large\bf\color{navy}{To~factorise:}$

$\tt{~~~~~~~~~~~~x^{2}+4x+3}$

$\bf\color{navy}{Here,~~S=4~~and~~P=3~~~(1~,~3)}$

$\tt{: \implies (x^{2}+x)+(3x+3)}$

$\tt{: \implies [x(x+1)~]+[3(x+1)~]}$

$\tt{: \implies (x+3)(x+1)}$

$\bf{ \therefore The~factors~are:~~(x+3)~~and~~(x+1)}$
