Can X equal a negative radical using the quadratic formula?
HotAnswerer
Yes any time 4ac > b2 then x will be a complex number
the curve represented by that formula will have no x intercepts.
Yes.

What is an easy way to go the quadratic formula?
the quadratic formula is really complex. so, if you can avoid it, you should. one way i do this is by getting the trinomial into X^2 - 2YX + Y^2 = 0 form. here's an example lets say we have x^2 - 2x - 5 = 0 normally we would have to do the quadratic formula however, if we get it into this form, we can get x^2 - 2(1)x + 1 = 6 all i did was add 6 to both sides of the equation. you can now simplify the left side of the equation, and be left with (x-1)^(2) = 6 to get ride of the exponent on the left side, find the square root of both sides. this will leave you with (x-1) = (+ or -)radical(6) add one to both sides and you will get x = 1 (+ or -)radical(6) therefore, x can equal 1 + radical(6) or 1 - radical(6) now, this may seem complex, but it is easy once you get used to it. It is far more efficient than the long quadratic formula.
Is there a formula for solving quadratic equations?
x is equal to negative b plus or minus the square root of b squared minus 4 times "a" times "c" all over 2 times "a"
What expressions appear as a step in solving 3x2 equal x-5 using the quadratic formula?
The following is the answer:
If the right-hand side of a quadratic equation does not equal zero you need to the number or expression on the righthand side from both sides before you can use the quadratic formula?
subtract
Where quadratic equation is applicable?
A quadratic equation in its general form of ax2+bx+c = 0 whereas 'a' is equal or greater than 1 is applicable when finding the unknown variable of x by using the quadratic equation formula.
How do you solve Quadratic functions?
All you do is set the quadratic function to equal to 0. Then you can either factor or use the quadratic formula to solve for your unknown variable.
Why can't an equal 0 in a quadratic equation?
a is the coefficient of the x2 term. If is a = 0, then it is no longer a quadratic - it is just a linear equation, and the quadratic formula will not work to solve it.
What is the entire quadratic formula?
the entire quadratic formula is x is equal to negative b plus or minus the square root b squared minus four(4) a c all over two(2) a (divided by 2)you may have trouble remembering this formula but you can fit it to the tune of pop goes the weasle.here ya go
What is x squared plus 1 equal negative seven x quadratic formula?
The first step to use the quadratic formula is to put your equation into standard form, meaning that you put everything to the left, and in descending order. In this case, you get: x^2 + 7x + 1 = 0 Which is the same as: 1x^2 + 7x + 1 = 0 So, the coefficients for the quadratic formula are: a = 1, b = 7, c = 1.

What statements must be true of an equation before you can use the quadratic formula to find the solutions?
That the discriminant of the quadratic equation must be greater or equal to zero for it to have solutions. If the discriminant is less than zero then the quadratic equation will have no solutions.

When solving a quadratic equation by factoring what method is used?
Start with a quadratic equation in the form � � 2 � � � = 0 ax 2 +bx+c=0, where � a, � b, and � c are constants, and � a is not equal to zero ( � ≠ 0 a =0).
How do you solve the quadratic equation -4y2 32y-64?
Do you mean -4y2+32y-64 = 0 otherwise it's not an equation because there's no equal sign If so then by using the quadratic equation formula the values of y both equal 4
