Question

Write the following equation in the form ax2+bx+c=then write the value of a b c x2-9x=13

Answer 1

Quadratic Equation

A quadratic equation in a variable $x$ is an equation which is of the form $ax^2 + bx + c = 0$ where constants a, b and c are all real numbers and $a \neq 0$.

Let us first write the given equation in the standard form of quadratic equation.

$\implies {x}^{2} - 9x = 13 \\ \\ \implies \boxed{{x}^{2} - 9x - 13 = 0}$

So this is our equation which is in the standard form of quadratic equation.

Now, comparing the equation with the standard form of quadratic equation, we get:

$\qquad \boxed{a = 1, \: b = -9, \: c = -13}$

Hence, this is our required solution.

Answer 2

Step-by-step explanation:

Quadratic Equation

A quadratic equation in a variable xx is an equation which is of the form ax^2 + bx + c = 0ax

2

+bx+c=0 where constants a, b and c are all real numbers and a \neq 0a



=0 .

Let us first write the given equation in the standard form of quadratic equation.

\begin{gathered}\implies {x}^{2} - 9x = 13 \\ \\ \implies \boxed{{x}^{2} - 9x - 13 = 0}\end{gathered}

⟹x

2

−9x=13

⟹

x

2

−9x−13=0

So this is our equation which is in the standard form of quadratic equation.

Now, comparing the equation with the standard form of quadratic equation, we get:

\qquad \boxed{a = 1, \: b = -9, \: c = -13}

a=1,b=−9,c=−13
