I am assuming the expression is (2x-3)(x+5) or (2x-3)(x-5). I will teach you how to solve for both as I am not sure which one you are asking for. There are 4 steps to multiplying.

1) Multiply the x times the second x
2) Multiply x times the second number
3) Multiply the number by the second x
4) Multiply the number by the second number.

(2x*x)+(2x*5)+(-3*x)+(-3*5)=(2
x^(2))+(10x)+(-3x)+(-15)=2
x^(2)+7x-15

(2x*x)+(2x*-5)+(-3*x)+(-3*-5)=(2
x^(2))+(-10x)+(-3x)+(15)=2
x^(2)-13x+15

Your answer is 2
x^(2)+7x-15 or 2
x^(2)-13x+15. Does that answer your question?
