Question

If (2x-5) (x+3) = 2x²+x+a, then the value of a is
​

Answer 1

Answer:

The value of a in the expression is $a=-15.$

Step-by-step explanation:

Expand

$(2x-5)(x+3)=2x^{2} +6x-5x-15$

                        $=2x^{2} +x-15$

comparing with $2x^{2} +x+a$, we get the value of

                 $a=-15$

Hence the answer
