'2 What is the true value 0f x2-X-2'
Added by Miguel -Ngel P.
Step 1
We can do this by finding two numbers that multiply to -2 and add up to -1. These numbers are -2 and 1. So, we can write: x^2 - x - 2 = (x - 2)(x + 1) Now, we can see that the expression can be simplified to: x^2 - x - 2 = (x - 2)(x + 1) = 0 This means that Show more…
