well 2 times 2 is 4.
you can say the four equal x and new new equation would be...
2 * 2 = x
4 = x
4x2-x+2x2 is 6x2-x when simplified
2x2-x-6 = (2x+3)(x-2)
8 - 2x2 = x + 22 - 7Combine like terms on the right side:8 - 2x2 = x + 15Subtract 8 from each side:-2x2 = x + 7Add 2x2 to each side:0 = 2x2 + x + 7
If that's + 2x2, the answer is x(x + 3)(x - 1) x = 0, -3, 1 If that's - 2x2, the answer is x(x - 3)(x + 1) x = 0, 3, -1
2x3 - 2x2 - x + 1 = 2x2(x -1) - (x - 1) = (x - 1)(2x2 -1) = (x - 1){[(sq. root of 2)(x)]2 -12} = (x - 1)[(sq. root of 2)(x) - 1][(sq. root of 2)(x) + 1]
x3 + 2x2 - 35x = x(x + 7)(x - 5)
What is the solution set of 2x2 + x = 15
2x2- 2x = 2x*(x - 1)
2x2 + (5x-4x)2 + (x-x)2 = 2x2 + x2 + 02 = 2x2 + x2 = 3x2
= Z X and Y are examples. 2 to the power of X multiplied by 2 to the power 2 equals 16 What is X? X=2 2 to the power of 2 (2x2) multiplied (X) by 2 to the power of 2 (2x2) (2x2)4 X (2x2)4 = 4X4 = 16
x3 - 2x2 + x - 2 =(x - 2)(x2 + 1)
2x2 + 17x - 9 = 2x2 + 18x - x - 9 = 2x(x + 9) - 1(x + 9) = (2x - 1)(x + 9)
