No.
'x' is +4 or -4 .
(2x - 1)(x + 4)
simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34
4 cubed is 64, 3 squared is 9, so 55.

'x' is +4 or -4 .
-2 times -2 = plus 4 since minus times minus is plus
(2x - 1)(x + 4)
simplified it would equal: 24x to the third power - x to the second power - x to the sixth power - 34
x^2(x - 4)(x + 4)
4 cubed is 64, 3 squared is 9, so 55.
7*6 + 22 - 32 = 42 + 4 - 9 = 37
50 * 5 = 250
-1 -2 multiplied by another -2 equals 4 .4-5=-1
10^2 minus 4 times 8 divided by 8 plus 9 is equal to 105.
