This year, 2009, minus birth year, 1947, equals 62.
xsquared minus x minus 72
If a equals 3 and b equals minus 5 then a minus b equals what
72 - 39 = 33
72 - 19 = 53
81
72
72 - k = 31 Therefore, k = 72 - 31 k = 41
81 - 72 = 9
-6 when you multiply two minus numbers the minus signs cancel each other out so -12 * -6 = 72
This year, 2009, minus birth year, 1947, equals 62.
xsquared minus x minus 72
350 minus 72 is 278.
If a equals 3 and b equals minus 5 then a minus b equals what
x2 - 21x = 72x2 - 21x - 72 = 0(x - 24) (x + 3) = 0x = 24x = -3
72-200-39 is equal to -167.
Using the quadratic equation formula the value of x is -8 or 5
