How do you solve using the completing the square method #3x^2 + 15x = 9#?
From the given
divide both sides of the equation by 3 first, to make the coefficient of
Divide now the numerical coefficient of x by 2 then square the result. Let the result be added to both sides of the equation
We now have the Perfect Square Trinomial
Extract square root of both sides
we have 2 values
God bless....I hope the explanation is useful.
