Solve 7w2 - 56 = 0, where w is a real number. Round your answer to the nearest hundredth. If there is more than one solution, separate them with commas. If there is no solution, click on "No solution".

w ≈ - 2.83, 2.83

Step-by-step explanation:

7w² - 56 = 0 ( add 56 to both sides )

7w² = 56 ( divide both sides by 7 )

w² = 8 ( take square root of both sides )

w = ±

Then x = - 2.83, x = 2.83 ( to the nearest hundredth )
