7C MINUS bracket open c plus 2 bracket close equals 7c minus c minus 2 equals 6c minus 2
(a + 5) (a - 5) = a2 - 25
hello
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.
15x minus 8=minus 180 3x+8=24
