2x-8=12
First you add 8 to both sides...
2x = 20
Then you divide each side by 2...
x = 20
Done

Wrong things...
- did not do the same thing to the entire side of each side
- wrong multiplication choice

Use the zero product property to find the solutions to the equation x^2-13x+30=0
Daniel [21]

We need to solve the zeroes of the given expression x² - 13x + 30 = 0 and we need to apply zero product property.First, we need to identify the two numbers which will result to -13 when added and it will result to 30 when multiplied. These two numbers are -3 and -10. Then, we can proceed with the solution such as:
x² - 13x + 30 = 0
(x-3) (x- 10) =0
From above, we have already the two zero product:
x-3 = 0
x1 = 3
x-10 =0
x2 =10

The answers are x1 = 3 and x2 = 10.
