The correct answer is 3.
2⋅3+12÷2^2−(4+2)
6+(12/2^2)-6
6+(12/4)-6
6+3-6
9-6
3
I assume that you mean a^2 + 2a - 3 = 0
You need to find two numbers that multiply together to give the number 3 and when added give the answer 2 (as in 2a). In this case the numbers are 3 and 1 (3 x 1 = 3 and 3 - 1 = 2)
Therefore we have
(a + 3)(a - 1) = 0
The values of x which solve the equation are -3 and 1
The reason is that -3 + 3 = 0 and 1 - 1 = 0 : zero times any number is zero
