15,000 to the third power that equals pi plus 12 would make it the square root of 7
It is a quadratic equation that has 2 solutions
perhaps they get confused because 2x2=4 and 2+2=4
2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0
17x2-11x+2 = 2x2 Subtract 2x2 from both sides: 15x2-11x+2 = 0 Factorise: (3x-1)(5x-2) = 0 Solution: x =1/3 or x = 2/5
2x2=4x4=16
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
x = (-1 ± √11) / 2
It is a quadratic equation that has 2 solutions
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.
perhaps they get confused because 2x2=4 and 2+2=4
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
