Here are possibilities of what you mean: a: (3-2)(x-2)=10 Solution: (3-2)(x-2)=10 1(x-2)=10 x-2=10/1 x=10+2=12 b: 3-2(x-2)=10 Solution: 3-2(x-2)=10 3-10=2(x-2) -7=2x-4 -3=2x x=-3/2=-1.5
5 x -2 = -10
3*x^2 + 2*x (where x=10)substitute 10 everywhere you see x. 3*(10^2) + 2*10 = 3*100 + 2*10 = 320
-2 times 5 = -10 1 x -10 2 x -5 5 x -2 10 x -1
2 x 10^4 x 2 x 10^4 x 2 x 10^4 = 8 x 10^12 8,000,000,000,000
