Question

a³+4a-3 factorise it step by step​

Answer 1

Step-by-step explanation:

as we know that in factorisation we need 4terms

so we will split the middle term into two parts

${a}^{3} + 1a + 3a - 3$

now we will take the common of

${a}^{3} + 1a$

AND

$3a - 3$

SO, by taking the common. we will solve

like

$a( {a}^{2} + 1) + 3(a - 1)$

so the answer will be

$(a + 3)( {a}^{2} + 1)$
