Equivalent expression without fraction
To do this, we simply multiply through by a common multiple of the denominators in the expression.
The denominators are 2 and 3
So, 6 is the least common multiple.
Multiply both sides by 6
<em>Hence, an equivalent expression.</em>
Answer:
D
Step-by-step explanation:
Given
f(x) = x² - 5x - 6
To find the zeros let f(x) = 0, that is
x² - 5x - 6 = 0
Consider the factors of the constant term (- 6) which sum to give the coefficient 0f the x- term (- 5)
The factors are - 6 and + 1, since
- 6 × 1 = - 6 and - 6 + 1 = - 5, thus
(x + 1)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
x - 6 = 0 ⇒ x = 6
