Answer:

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s). Examples.

Solve for x: 2x ^ 3 - x ^ 2 + 18x - 9 = 0

frozen [14]

Answer:

see explanation

Step-by-step explanation:

Given

2x³ - x² + 18x - 9 = 0 ( factor the first/second and third/fourth terms )

x²(2x - 1) + 9(2x - 1) = 0 ← factor out (2x - 1) from each term

(2x - 1)(x² + 9) = 0

Equate each factor to zero and solve for x

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = $\frac{1}{2}$

x² + 9 = 0 ⇒ x² = - 9 ⇒ x = ± 3i

The equation has 1 real solution and 2 complex solutions

x = $\frac{1}{2}$ ← real solution

x = ± 3i ← complex solutions
