2 sqared is 4 so 2x2 sqared is 4
2x2-2 = -5x-1 2x2+5x-2+1 = 0 2x2+5x-1 = 0 Use the quadratic equation formula to find the values of x: x = 0.1861406616 or x = -2.686140662
2x2-x-6 = (2x+3)(x-2)

y
(2x2 - 1)(2x2 - 1) or (2x2 - 1)2
2x2 = 4 , Four . 2x2 = 4 , Four .

2x2=4 X -2=-8
2 sqared is 4 so 2x2 sqared is 4
= 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
2x2-2 = -5x-1 2x2+5x-2+1 = 0 2x2+5x-1 = 0 Use the quadratic equation formula to find the values of x: x = 0.1861406616 or x = -2.686140662
x3 - 2x2 + x - 2 =(x - 2)(x2 + 1)
2x2 (2=76)
2 x 2 = 4 and you will know that byyyyy counting 2 plus 2 and that give you 4 and you can do 2,4,6,8,10
