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
2x2=4x4=16

x = (-1 ± √11) / 2
If: 2x2-3x+1 = 0 Then: x = 1 or x = 1/2
6x3 - x2 + 17 = 2x2 + 47 6x3 - x2 - 2x2 = 47 - 17 x2(6x - 1 - 2) = 30 this is the simplest factorisation.

2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0
-2x^2 = -50 x^2 = 25 x = 5, -5
2x2+4 and 2+2+4 because counting by 2's 2,4
x2 plus 6x-2 equal -2x2 plus x ..=7x equal -3x2 ..4x=2x=2 answer ..check it if u dont want to trust ..Improved Answer:x2+6x-2 = -2x2+xx2+2x2+6x-x-2 = 03x2+5x-2 = 0(3x-1)(x+2) = 0x = 1/3 or x = -2The answer can be checked by using the quadratic equation formula.
