2 time 4 3
4x * x = 4x^2
It can't be simplified any more. That is the answer, 3*4X or 12x
4x^2
4x
4x^2
2(4x-1)=18 is the question. In this case, x=2.5
Let the unknown number be x: 4x-2 = -7 4x = -7+2 4x = -5 x = -1.25
4x
4x × 4x = (4x)² = 16x²
(4x - 1)(4x + 1)
Let the number be x: 4x-2 = 6x+2 4x-6x = 2+2 -2x = 4 x = -2
2 (2x) = 4x
