What're examples of quadratic equation?
x*2+4x+8= 0 is a quadratic equation
Is the equation x2 plus 2x plus 1 quadratic?
It is a quadratic expression and when factored is: (x+1)(x+1)
Is 3x plus 27 equals 8 a quadratic function?
No it is a linear one. X^2 = quadratic, x = linear. So if the equation doesn't have an x squared, then it is not quadratic.
Is x squared plus 3x -y 8 a linear equation?

What are the solutions for the quadratic equation x2 minus 8x equals 9?
To solve a quadratic equation (which means to find the zeros of that equation) you have two options 1. type the equation into a graphing calculator and graph the resulting equation and find where the x intercepts are (where y=0) 2. solve the quadratic equation by factoring First, set the equation equal to zero. x2-8x-9=0 Then find the resulting x values by "smiling" multiply the first term and the last term (x2) (9) find two numbers that add to -8 and multiply to -9 these two numbers are -9 and 1 x2- 9x 1x-9 x(x-9) 1(x-9) the resulting factors are 0= (x+1)(x-9) to find the roots, set these factors = 0 x+1=0 x=-1 x-9=0 x=9 Therefore, the solutions for the quadratic equation are x=-1 and x=9

Can you solve 3x2-x equals -1?
Set the equation equal to zero. 3x2 - x = -1 3x2 - x + 1 = 0 The equation is quadratic, but can not be factored. Use the quadratic equation.
Is the equation x2 plus 2x plus 1 quadratic?
It is a quadratic expression and when factored is: (x+1)(x+1)
Is 3x plus 27 equals 8 a quadratic function?
No it is a linear one. X^2 = quadratic, x = linear. So if the equation doesn't have an x squared, then it is not quadratic.
Sin Squared x plus cos x equals 0 for x is a part of 1 to 360 degrees?

Is -2x squared plus 2x plus 1 equals 9 a quadratic equation?
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
How do you solve a quadratic equation graphically?
The roots of the quadratic equation are the x-intercepts of the curve.
What are the factors for the quadratic equation x2 plus 5xMinus24?
x2+5x-24 = (x-3)(x+8)
What are the roots of the quadratic equation x2 - 6x plus 8 equals 0?
x = 2 and x = 4
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.
