No.
12 - 4 = (1 * 1) - 4 = 1 - 4 = -3
4 cubed is 64, 3 squared is 9, so 55.
'x' is +4 or -4 .

4 cubed is 64, 3 squared is 9, so 55.
7*6 + 22 - 32 = 42 + 4 - 9 = 37
4-3 = 1/64

-2 times -2 = plus 4 since minus times minus is plus
(2x - 1)(x + 4)
when you're doing a problem like that use this trick. let's say you have 3 to the -7 power minus 3 to the 4 power. -7 - 4 can also be shown as -7 + -4. i switched the minus sign to a plus sign and because i did that, i had to switch the positive 4 to a negative 4. so i got 3 to the -7 power plus 3 to the -4 power.
simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34
(6 x 5) - (3 x 52) + (12/4) = 30 - 75 + 3 = -42
