The quadratic equation whose roots are -6 and 6, and whose leading coefficient is 2 is 2x^2 - 72 = 0.

Roots are -6 and 6, then (x + 6)(x - 6) = 0

Leading coefficient is 2, then (2x + 12)(x - 6) = 0

Simplify the equation: 2x^2 - 72 = 0

Roots are -6 and 6, then (x + 6)(x - 6) = 0

The sum of two numbers is 62 and the difference is 14. What are the numbers? **Weegy:** The sum of two numbers is 62 and the difference is 14. The numbers are 38 and 24.
38+24=62. 38-24=14 (More)
