SIMPLIFY: s^2+4s-4
To simplify the expression s^2 + 4s - 4, we can factor it if possible or use the quadratic formula to find the roots. Let's start by checking if it is factorable:
To factor the expression, we are looking for two numbers whose sum is 4 and whose product is -4. The factors of -4 are -1 and 4 or 1 and -4. Since we want a positive 4 when multiplied, we can use -1 and 4.
Thus, the expression s^2 + 4s - 4 can be factored as (s + 2)(s - 2).
So, the simplified expression is (s + 2)(s - 2).
