Solve the given expression for x = -18:5x/3 - 2

Keith_Richards [23]

ANSWER

$-32$

EXPLANATION

We want to solve the given expression for x = -18:

$\frac{5x}{3}-2$

To do this, substitute the given value of x into the expression and simplify. That is:

$\begin{gathered} \frac{5(-18)}{3}-2 \\ \frac{-90}{3}-2 \\ -30-2 \\ \Rightarrow-32 \end{gathered}$

That is the answer.

Complete the square for 5x^2-30x=5

Nikitich [7]

Solve for x over the real numbers: by completing the square:

5 x^2 - 30 x = 5

Divide both sides by 5:

x^2 - 6 x = 1

Add 9 to both sides:

x^2 - 6 x + 9 = 10

Write the left hand side as a square:

(x - 3)^2 = 10

Take the square root of both sides:

x - 3 = sqrt(10) or x - 3 = -sqrt(10)

Add 3 to both sides:

x = 3 + sqrt(10) or x - 3 = -sqrt(10)

Add 3 to both sides:

Answer: | x = 3 + sqrt(10) or x = 3 - sqrt(10)
