a2 + 2a - 3 = 0
(a + 3)(a - 1)
a = - 3
a = 1
Simple factoring where you ask yourself; what two factors of - 3 add up to 2?

hello
x = 25 / 3squared + 5
Solve this problem -x squared -40x- 80 =0
Your Problem: X - 4 = ?Current Problem: 3 [squared] - 4 = ?How: When a numbered is squared, it means you multiply it against itself. So, 3 squared equals 3x3.3x3 = 9So, you would then take 9 and minus it by 4, which would than equal 5.Answer:3 [squared] - 4 = 5or9 - 4 = 5
Solve using the quadratic formula
X=1
If x squared -10 = 0 then x = the square root of 10

Without an "equals" word or sign somewhere, there is nothing to solve.You only have an expression, not an equation.
It can be solved by using the quadratic equation formula.
(-1/6) - 2/3 = -0.8333333332
