Question

2a^2 + 3a + 1

factorise
​

Answer 1

Answer:

2a^2+3a+1=0

2a^2+2a+a+1=0

2a(a+1)+1(a+1)=0

2a+1=0,a+1=0

a=-1/2,a=-1

Answer 2

Answer:

For a polynomial of the form ax2+bx+cax2+bx+c, rewrite the middle term as a sum of two terms whose product is a⋅c=2⋅1=2a⋅c=2⋅1=2 and whose sum is b=3b=3.
