2x2 - 72 would be factored into (2x - 12)(x + 6) or (2x + 12)(x - 6) To double check, multiply each pair: (2x - 12)(x + 6) = 2x2 + 12x - 12x - 72 = 2x2 - 72 (2x + 12)(x - 6) = 2x2 - 12x + 12 x - 72 = 2x2 - 72
As an equation if: 6x = 72 then x = 12
x2 - 18x + 72 = 0 (x - 6)(x - 12) = 0 x ∈ {6, 12}
-12x = 72 Divde both sides by -12 to find the value of x: x = -6
12 x 6 = 72 cm squared.
12 x 72 = 864
2x2 - 72 would be factored into (2x - 12)(x + 6) or (2x + 12)(x - 6) To double check, multiply each pair: (2x - 12)(x + 6) = 2x2 + 12x - 12x - 72 = 2x2 - 72 (2x + 12)(x - 6) = 2x2 - 12x + 12 x - 72 = 2x2 - 72

12 x 6 = 72
percentage_increase = (new - old)/old x 100 % = (72 - 12)/12 x 100 % = 500 %
90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
1 x 72 = 72 2 x 72 = 144 3 x 72 = 216 4 x 72 = 288 5 x 72 = 360 6 x 72 = 432 7 x 72 = 504 8 x 72 = 576 9 x 72 = 648 10 x 72 = 720 11 x 72 = 792 12 x 72 = 864
12 × 72 = 864.
