15,000 to the third power that equals pi plus 12 would make it the square root of 7

2x2 + 10 = 9x 2x2 - 9x + 10 = 0 (x - 2)(2x - 5) = 0

It is a quadratic equation that has 2 solutions

6x3 - x2 + 17 = 2x2 + 47 6x3 - x2 - 2x2 = 47 - 17 x2(6x - 1 - 2) = 30 this is the simplest factorisation.

perhaps they get confused because 2x2=4 and 2+2=4
