The quadric equation is: negative b plus or minus the square root of b squared minus 4ac all over(divided by) 2a
No, it is the discriminant of a quadratic equation.
The discriminant b2-4ac is -23
negative b plus or minus the square root of b squared minus 4AC all over 2 A
it's the bit in the square root sqrt of (b squared minus 4ac) when a,b and c are the values belonging to the equation ax(sqared) plus bx plus c
Depends what type of equation you want. My favourite is the quadratic equation. (-B plus or minus the square root of B - 4AC) Divided by 2A
Use (-b + or - sqrt(b^2-4ac))/(2a) A is 10 B is -9 C is -6
The discriminant, because it helps you to discriminate between the type (and number) of roots.
the general form of quadratic equation is ax^2+bx+c therefore the formula for factorisation is =-b+(or)-sqrt(b^2-4ac)/2a on applying this formula we get the roots as:1/2+(or)-sqrt(5)/2
midpoint: (x1+x2/2 , y1+y2/2) quadratic: -b plus or minus square root b squared minus 4ac divided by 2a
Using the quadratic formula to solve any quadratic equation is the best way of getting around it because the quadratic formula is "the opposite of b plus or minus the square root of b squared minus 4ac all divided by 2a. This formula only works with trinomials and second degree equaitons. If the equation is a binomial, then put in a placeholer (0) and substitute them into the equation.
1. if your equation is not in standard form make it in standard form. ax squared +/- bx +/- c. abc repesent numbers and x always represents the variable. 2.than plug in abc in the following equation: -b +/- sqaure root of 4ac divided by 2a. 3. do plus and minus and those are your roots ( answers) 4. note: if the discriminant ( the square root of 4ac) is not positive there will be no roots.
