Solve for x in the equation below(all in picture).
EleoNora [17]

Answer:

x = - 5, x = 2

Step-by-step explanation:

Using the rules of logarithms

log x - log y = log (\frac{x}{y} )

log_{b} x = n ⇔ x = b^{n}

note that log x = log_{10} x

Given

log (x² + 3x) - log10 = 0, then

log(\frac{x^2+3x}{10} ) = 0, thus

\frac{x^2+3x}{10} = 10^{0} = 1 ( multiply both sides by 10 )

x² + 3x = 10 ( subtract 10 from both sides )

x² + 3x - 10 = 0 ← in standard form

(x + 5)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 2 = 0 ⇒ x = 2

Solution is x = - 5, x = 2
