SOLVING QUADRATIC EQUATION BY QUADRATIC FORMULA: Q1 W1 PART 4
In this video, we are going to learn a lot about What is Quadratic Formula? This will include about the numerical coefficients, Quadratic formula explanation, getting two answers of quadratic formula, the discriminant, solve an equation with real solutions and lastly solve an equation with a complex answer.
COMMENT down if you would like a COPY of the POWERPOINT I used in the video, I would be glad to SHARE. ☺️
