Question

Factorise it a2+2a-3 ​

Answer 1

Step-by-step explanation:

$a {}^{2} + 2a - 3 \\ a {}^{2} + 3a - a - 3 \\ a(a + 3) - 1(a + 3) \\ (a + 3)(a - 1) \\ a + 3 = 0 \: \: and \: \: a - 1 = 0 \\ a = - 3 \: \: \: and \: \: a = 1$

this is the answer

Answer 2

Answer:

Given a²+2a-3

Step-by-step explanation:

a²+2a-3 =a²+3a-a -3

=a(a+3) - 1(a+3)

=(a+3) (a-1)

So, a= -3 and a = 1
