Question

Solve 25x^2-30=0

Answer 1

Answer:

x = - 1.10 and x = 1.10

Step-by-step explanation:

Given

25x² - 30 = 0 ( add 30 to both sides )

25x² = 30 ( divide both sides by 25 )

x² = $\frac{30}{25}$ ( take the square root of both sides )

x = ± $\sqrt{\frac{30}{25} }$

x = - 1.10 and x = 1.10 ( to the nearest hundredth )
