4x^2 - 12x + 9 = 0
(2x - 3)(2x - 3) = 0
Someone solve this for me pleasee solving using quadratic formula?
please someone explain this to me and be as descriptive as possible i would really appreciate.
i know i have to plug them in into the quadratic formula but every time i solve this i always get a different answer and i dont get why please someone explain this to me or do it to me so i know what im doing wrong
Now when you substitute values into the quadratic formula, the discriminant ( ) determines the amount of 'roots' or answers there are because of the plus/minus before it.
If the discriminant is above 0, there are 2 answers.
If the discriminant is equal to 0, there is 1 answer.
If the discriminant is below 0, there are 0 answers.
A typical quadratic equation is:
Now from your equation, can you determine for yourself what the value of a, b and c are to put into the quadratic formula?
