When is an equation quadratic?
When the equation is in one the following formats: ax2+ bx+c = 0 a(x+b)2+c = 0 (x+a)(x+b) = 0 than it is a quadric. It is also quadratic when x2 and only x2 is in it. example: x2 + 1= 0 and x2=0 are quadratic equations. However ax3+bx2+ cx+d =0 is not a quadratic, this is a cubic because of the x3 term, However you can use the quadric equation to find one of the two answers for it.
How are functions like linear equations?
Most functions are not like linear equations.
What is the quadric equation for x2-2x-13 equals 0?
x = 4.74 or -2.74
What is the range of the continuous quadric function y6x2 plus 5?
The range is y >= 5.
If the discriminant is zero the graph of a quadric function will cross or touch the x axis how many times?
It will touch it once.
Examples for quadric equation?
The quadric equation is: negative b plus or minus the square root of b squared minus 4ac all over(divided by) 2a
