If x = 4
Then 7x - 2 =

120 x (1/4) =

15 x (7 + (-3)) =

x^2 + 3x + 2 = (x + ) (x - )

2[3 + (1016/2)] =

(x + 3)(x - 8) = x^2 - 5x -

3^4 =

(23 + 26) / (2 x 4 -1) =

7 x (12-3) + 8 =

(square root of 225) x 15 =

[(6 x 7) - 20] / 2 =

(28 / 7) + 272 -11 =

(99 / 2) + 4.5 - 7 =

2 x 3 x 4 x 6 =

(2 + ) x 8 = 72

x 7 - 13 = 15

((15 x 5 - 6) + 100) / 13 =
