1A [blank_start]quadratic equation[blank_end] in one variable is a mathematical sentence of degree 2 that can be written in the following standard form.
- Aquadratic equation
2ax^2 + bx + c =0, where a,b, and c are [blank_start]real numbers[blank_end] and a=\0
- Areal numbers
3In the equatiob, ax^2 is the [blank_start]quadratic term[blank_end], bx is the [blank_start]linear term[blank_end], and c is the [blank_start]constant term[blank_end].
- Aquadratic term
- Blinear term
- Cconstant term
4When b=0 in the explanation ax^2 + bx + c=0, it results to a quadratic equation of the form [blank_start]ax^2 + c=0[blank_end]
- Aax^2 + c=0
5The method of solving the quadratic equation x^2 = k is called [blank_start]extracting square roots[blank_end].
- Aextracting square roots
6[blank_start]Zero product property[blank_end]
If the product of two real numbers is zero, then either of the two is equal to zero or both numbers are equal to zero.- AZero product property
7Another method of solving quadraric equations is by completing square. This method transforms the quadratic equation into [blank_start](x-h)^2[blank_end].
- A(x-h)^2
8The solution for quadratic formula is
[blank_start]x= -b +- √b^2 -4ac / 2a[blank_end]- Ax= -b +- √b^2 -4ac / 2a
9[blank_start]b^2 -4ac[blank_end] is called the discriminant of the quadratic equstion ax^2 + bx + c=0
- Ab^2 -4ac
10The solution to get the sum of the roots is [blank_start]-b/a[blank_end] and for the product [blank_start]c/a[blank_end]
- A-b/a
- Bc/a
11An [blank_start]extraneous root[blank_end] or [blank_start]solution[blank_end] is a solution of an equation derived from an original equation.
- Aextraneous root
- Bsolution
