The expression we get after factorising 2x2+x−3 is ___
(2x+3)(x−2)
(2x+3)(x−1)
(5x+3)(x−1)
(2x+3)(8x−1)
Multiply (2x+3) and (x−1). We get..
(2x+3)(x−1)=2x2−2x+3x−3=2x2+x−3
(2x+3)(x−1) is the required expression.
The polynomial equation P(x)= 3x2+5x+2 can be represented as
The polynomial equation P(x)= 3x2+10x+7 can be represented as
