Answer :
9x^2 = 17...divide both sides by 9
x^2 = 17/9 or 1.89....take square root of both sides, eliminating the ^2
x = (+-) sqrt 1.89
x = (+-) 1.37 <==
x^2 = 17/9 or 1.89....take square root of both sides, eliminating the ^2
x = (+-) sqrt 1.89
x = (+-) 1.37 <==
The solution of the given quadratic equation is x = 1.37, - 1.37.
What is a quadratic equation?
"A quadratic equation is an algebraic equation of the second degree in any variable."
Given quadratic equation:
9x² = 17
⇒ x² = (17 / 9)
⇒ x = ± √(17 / 9)
⇒ x = ± (√17) / 3
⇒ x = 1.37, - 1.37
