There are 49 gallons of red paint.
I figured it out by doing the following:

If you subtract the gallons of pink paint (21) from the total number of gallons (70), then you get the number of gallons of red paint (49) because 49 + 21 = 70. I hope that helps :)
You could just factor out the Trinomial and find the zeros of the equation,
x^2 - 2x -15 = (x - 5)(x + 3) = 0,
x - 5 = 0 and x + 3 = 0, so x = 5,-3 AKA answer choice C
