what is the c term in a quadratic equation C is the constant or the term without any x next to it so here c 21 Then we plug a b and c into the formula x 4 16 4 1 21 2 solving this looks like x 4 100 2 4 10 2 2 5 Therefore x 3 or x 7 What does the solution tell us
In algebra a quadratic equation from Latin quadratus square is any equation that can be rearranged in standard form as 1 where x represents an unknown value and a b and c represent known numbers where a 0 If a 0 and Coefficients are a 1 b 4 c 6 25 Note that the Discriminant is negative b2 4ac 4 2 4 1 6 25 9 Use the Quadratic Formula x 4 9 2 9 3 i where i is the imaginary number 1 So x 4 3i 2 Answer x

The quadratic equation in its standard form is ax 2 bx c 0 where a and b are the coefficients x is the variable and c is the constant term The important condition for an equation to be a quadratic equation is the coefficient of x 2 is a non zero term a 0 The Quadratic Formula is a rule that says that in any equation of the form ax2 bx c 0 the solution x values of the equation are given by x dfrac b pm sqrt b 2 4ac 2a x 2a b b2 4ac
About Transcript The quadratic formula helps us solve any quadratic equation First we bring the equation to the form ax bx c 0 where a b and c are coefficients Then we plug these coefficients in the formula b b 4ac 2a See examples of using the formula to solve a variety of equations Created by Sal Khan Questions It looks like this x b b 2 4 a c 2 a where a b and c refer to the coefficients in a quadratic equation written in standard form a x 2 b x c Practice with our Quadratic formula exercise

Quadratic equation The standard form of a quadratic equation is ax 2 bx c 0 where a 0 In the equation a b and c are constants and x is a variable The degree of the equation 2 the exponent on x makes the equation quadratic Solve using the quadratic formula 2 x 2 7 x 15 0 Solution Begin by identifying the coefficients of each term a b and c a 2 quad b 7 quad c 15 Substitute these values into the quadratic formula Equation ref quad and then simplify
A quadratic equation in two variables where a b and c are real numbers and a 0 is an equation of the form y ax 2 bx c Square Root Property The Square Root Property states that if x 2 k and k 0 then x sqrt k or x sqrt k A quadratic equation is expressed in standard form if all the variables and coefficients are found on one side of the equation and the opposite across the equal symbol is just zero That is if possible we rewrite and rearrange any equation into the form color red ax 2 bx c 0 ax2 bx c 0
