Identify expression: Identify the expression to be simplified.The expression given is (2x2−11x−6)/(x−6). We need to simplify this expression by performing polynomial division or factoring, if possible.
Check for factoring: Check if the numerator can be factored.We will attempt to factor the quadratic expression 2x2−11x−6. To factor, we need two numbers that multiply to 2∗(−6)=−12 and add up to −11.
Find factors: Find the factors of the quadratic expression.The factors of −12 that add up to −11 are −12 and +1. So we can rewrite the quadratic expression as 2x2−12x+x−6.
Group terms to factor: Group the terms to factor by grouping.(2x2−12x)+(x−6) can be grouped to factor out common terms.
Factor out common terms: Factor out the common terms from each group.From the first group, we can factor out 2x, and from the second group, we can factor out 1.2x(x−6)+1(x−6)
Factor out binomial factor: Factor out the common binomial factor.We can now factor out the common binomial factor (x−6) from the expression.(2x+1)(x−6)
Simplify expression: Simplify the original expression by canceling out the common factors.Now we can cancel the (x−6) term in the numerator with the (x−6) term in the denominator.The simplified form is (2x+1).
