Answer:
x^2 -x -2 = (x -2)(x +1)
Step-by-step explanation:
To factor x^2 -x -2, you look for factors of -2 that have a sum of -1:
-2 = (-1)(2) = (1)(-2) . . . . . the latter pair has a sum of -1
Then these are the constants in the binomial factors:
x^2 -x -2 = (x +1)(x -2)

<em>Comment on the question</em>
The fact that x^2 +3x -4 is modeled with algebra tiles seems to be irrelevant to the question that is actually asked.
To figure out you would first find a common factor with would be 12. After that 1/4 would be 3/12, 1/3 would be 4/12 and 1/6 would be 2/12. Next you just add all the numbers and get 9/12 then the remainder is you answer which comes to be 3/12 or 1/4. Hope that helps:)
The expression of all the algebra as single rational exponent are; As written below.
<h3>How to Express Exponents?</h3>
1) We want to express ⁴√x³. This can be expressed as;
x^(3/4)
2) We want to express the exponent ¹/x⁻¹. This is expressed as a single rational exponent as; x
3) We want to have the given expression as a single rational exponent. The expression is; ¹⁰√(x⁵ · x⁴ · x²)
We add the exponents to get;
¹⁰√(x¹¹) = x^(¹¹/₁₀)
4) x^(¹/₃) * x^(¹/₃) * x^(¹/₃)
We just add the exponents to get;
x¹ = x
