The quadratic formula is "[minus b] over 2a, plus or minus the square root of [b squared minus 4ac], over 2a".
where the formula for the variable is in the form
a(x2) + b(x) + c = 0
By setting the equation into this form, you can use the integer values a, b, and c to find the solution for x, simply by multiplying, taking the square root, and adding. As the equation describes a curve, the two solutions (plus or minus) are the x-intercepts (y=0) of the curve, and the y-intercept (x=0) is at c.
* For the shorter form ax2 + 2kx + c where k is an even number, see the related link.

2a -3 plus 4b - 2a -b -3 plus 5?
2a-3+4b-2a-b-3+5=3b-1
What is b squared minus 4ac called in the quadratic formula?
The discriminant, because it helps you to discriminate between the type (and number) of roots.
Find all complex solutions for the equation x2 equals 4x - 29?
Use the quadratic formula. In x2 - 4x + 29 = 0, a is 1, b is -4, c = 29. The quadratic formula is: x = (-b plusminus squareroot(b2 - 4ac)) / 2aUse the quadratic formula. In x2 - 4x + 29 = 0, a is 1, b is -4, c = 29. The quadratic formula is: x = (-b plusminus squareroot(b2 - 4ac)) / 2aUse the quadratic formula. In x2 - 4x + 29 = 0, a is 1, b is -4, c = 29. The quadratic formula is: x = (-b plusminus squareroot(b2 - 4ac)) / 2aUse the quadratic formula. In x2 - 4x + 29 = 0, a is 1, b is -4, c = 29.

X squared - 4x - 21?

F x x2 x 2 To find the x intercept let f x 0 and solve for x Factor complete the square or use the quadratic formula?
the quadratic formula is [ neg. b plus or minus the square root of (b squared minus 4ac) ] all divided by 2a ur question doesnt have and =, +, or - so it cant be effectively solved
