x²+3x+2.. factorise the question with identies...​

Answer 1

x²+3x+2

Explanation:

Note that in general:

(x+a)(x+b)=x2+(a+b)x+ab

So can we think of two numbers a,b such that a+b=3 and ab=2 ? How about 1 and 2 ?

So:

x2+3x+2=(x+1)(x+2)

Answer 2

Step-by-step explanation:

x2 +3x+2

x2+x+2x+2

x(x+1)2(x+1)

x2= x square
