Answer:
Explanation:
3x2+17x+10
We can Split the Middle Term of this expression to factorise it.
In this technique, if we have to factorise an expression like ax2+bx+c, we need to think of 2 numbers such that:
N1⋅N2=a⋅c=3⋅10=30
and,
N1+N2=b=17
After trying out a few numbers we get N1=15 and N2=2
15⋅2=30, and 15+2=17
3x2+17x+10=3x2+15x+2x+10
=3x(x+5)+2(x+5)
(3x+2)(x+5) is the factorised form of the expression.
