What is the Standard Form of a Quadratic?

A quadratic polynomial is a polynomial where the highest degree term is an x² term
All like terms must be combined and the degree of each term decreases from left to right
A, B, and C are coefficients
8x²-10x+3 is in standard form because the like terms are combined, the degree decreases from left to right
4x²-9 can be rewritten as 4x²+0x-9
4x²+0x-9 is in standard form because the like terms are combined, the degree decreases from left to right, and A≠0

1. A, B, and C are coefficients
1. A quadratic equation must have an x² term
2. If A is 0, then this would not be a quadratic polynomial because there would be no x² term
1. A the coefficient for x²
2. B the coefficient for x¹, which is just x
3. C the coefficient for x⁰, which is just 1
1. For 8x²-10x+3 to be in standard form...
2. All like terms must be combined and the degree of each term decreases from left to right
1. All like terms must be combined and the degree of each term decreases from left to right
1. All like terms must be combined for the first criterion
1. A is 8, B is -10, and C is 3
2. A, B, and C are coefficients
1. A, B, and C are coefficients
2. Notice that A≠0, which is also necessary for an equation to be in standard form
1. 8x²-10x+3 is in standard form
1. For 4x²-9 to be in standard form...

1. The degree of each term decreases from left to right for the second criterion
1. A, B, and C are coefficients
1. A is 4, B is 0, and C is -9
2. A, B, and C are coefficients
