# Math Help - Is my quadratic correct for this example?

1. ## 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.

2. x times (x + 3) = 10
x^2 + 3x - 10 = 0 : kapish?

Let the numbers be x and x+3.

$x(x+3)=10$;

$x^2+3x-10=0$

4. Yes, I understand Product of, oh, woops, I was thinking addition, silly me

Can I solve this with the quadratic formula?

Thanks again!

5. You can but this one factors to $(x+5)(x-2)=0$
