Methods of solving quadratic equations
There are four methods of solving quadratic equations. i) By factorization ii) By completing the squares iii) By using the formula iv) By graphi..
Equations reducible to quadratic form
Type 1 - Equations of the form In such equations, put x n = t then the equation reduces to at 2 + bt + c = 0. Solve for t and then obtain the value of ..

Quadratic is another name for the 2nd degree polynomials. The product of two linear factors gives a quadratic trinomial; and the factors of a quadratic trinomial are linear factors (Binomial..
Use the Quadratic Formula to Solve a Quadratic EquationLearn how to use the quadratic formula to solve a quadratic equation.
Solving a Quadratic Equation by the Quadratic FormulaUsing the Quadratic Formula to solve a quadratic equation. Use this method if you are weak at factoring, or if the equation is difficult to factor or cannot be factored. This is video 36 of 51 in the solving equation series. The next three series are "Word Problems", "Factoring" and "Graphing".
Question : the equation is like this x^2+9=0 in quadratic formula you would have A,B,C right? but if A in this equation is 2 and C is 9 what is B? is it zero? or is it 9 and C is zero?
Answer : x^2+9=0 a=1 b=0 c=9 .....-b [b^2-4ac] x=------------------------- ............2a .....-0 [(0)^2-4(1)(9)] x=------------------------------ ..........2(1) ...... (-36) x=------------------- ........2 ..... 6i x=-------= 3i ......2 x=3i, -3i answer//

Question : i know how to find the y intercept, i want to know a formula for it, so i can make a program on my calculator to do it for me...
Answer : The y intercepts are always found by setting x=0 and solving. consider f(x)=x^2-4x+4 y=x^2-4x+4 set x=0 the y intercept is y=4
