    Is my quadratic correct for this example?

    1. The product of two numbers is 10. One number is 3 more than the other number. What is the quadratic equation that models these numbers?

    x^2 + 3 = 10 ???????????????????

    If not, please let me know what it is. I have been struggling with this question for 30 minutes.

    x times (x + 3) = 10

    Let the numbers be x and x+3.

    x(x+3)=10;

    x^2+3x-10=0
