X2 9 can be described mathematically to be a quadratic function.
Rearrange the quadratic equation to: x2-6x-9 = 0 and use the quadratic equation formula to find the values of x which are:- x = -1.2426406871 or x = 7.2426406871 When factored: (x+1.2426406871)(x-7.242406871) = 0
That doesn't factor neatly. Applying the quadratic formula, we find two imaginary solutions: -3 plus or minus i, where i is the square root of negative 1.
x2 - x - 1 doesn't factor. Applying the quadratic formula, there are two real solutions:(One plus or minus the square root of five) divided by two.x = 1.618033988749895x = -0.618033988749895
That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: 3 plus or minus 2 times the square root of 2x = 5.82842712474619x = 0.1715728752538097
X2 9 can be described mathematically to be a quadratic function.
x2
x2+11x+11 = 7x+9 x2+11x-7x+11-9 = 0 x2+4x+2 = 0 The above quadratic equation can be solved by using the quadratic equation formula and it will have two solutions.
6x5(x2 - 6x + 3)
It is a quadratic expression and when factored is: (x+1)(x+1)
x2 - 8x + 32 = 0 (assuming)you can factor or use the quadratic equation.I recommend the quadratic equation.
If the highest exponent of independent variable(say x) is 2 and the highest exponent of dependent variable(say y) is 1 and x and y are not multiplied, then the function is quadratic. For example: 3x-y+x2= 2y-5x+7 represents a quadratic function but y= xy+x2+5 doesn't represent a quadratic function.

y = x2 is the parent function, but it can be in the form y = ax2 + bx + c
A quadratic function is a function where a variable is raised to the second degree (2). Examples would be x2, or for more complexity, 2x2+4x+16. The quadratic formula is a way of finding the roots of a quadratic function, or where the parabola crosses the x-axis. There are many ways of finding roots, but the quadratic formula will always work for any quadratic function. In the form ax2+bx+c, the Quadratic Formula looks like this: x=-b±√b2-4ac _________ 2a The plus-minus means that there can 2 solutions.
It is a quadratic polynomial with integer coefficients..
