All literal equations have how many variables ?

Mathematics

<u>Answer:</u>

more than one variable (two or more)


<u>Explanation:</u>

<u>Literal equations</u> are used to represent a known quantity/value using unknown values.


Now,<u> if we have only one variable</u>, then this variable will no longer be unknown as it will be equal to the known quantity. This means that the equation will not be literal.

<u>Example:</u>

Number of tickets is 25.

x = 25 where x is the number of tickets


If we have<u> two variable</u>, neither of them will be known. This means that the equation will be literal.

<u>Example:</u>

Number of apples added to number of bananas is 15.

x + y = 15

where x is the number of apples and y is the number of bananas, neither of them is known.


<u>Based on the above,</u> the literal equation must have more than one variable (two or more)


Hope this helps :)

Answer – Two or more variables (In other words, More than one variable)

In simple terms, literal equations are equations containing two or more variables; at least one independent variable and one dependent variable. In essence, all literal equations have more than one variable.

Solve the following equation by factoring:9x^2-3x-2=0
olya-2409 [2.1K]

Answer:

The two roots of the quadratic equation are

x_1= - \frac{1}{3} \text{ and } x_2= \frac{2}{3}

Step-by-step explanation:

Original quadratic equation is 9x^{2}-3x-2=0

Divide both sides by 9:

x^{2} - \frac{x}{3} - \frac{2}{9}=0

Add \frac{2}{9} to both sides to get rid of the constant on the LHS

x^{2} - \frac{x}{3} - \frac{2}{9}+\frac{2}{9}=\frac{2}{9}  ==> x^{2} - \frac{x}{3}=\frac{2}{9}

Add \frac{1}{36}  to both sides

x^{2} - \frac{x}{3}+\frac{1}{36}=\frac{2}{9} +\frac{1}{36}

This simplifies to

x^{2} - \frac{x}{3}+\frac{1}{36}=\frac{1}{4}

Noting that (a + b)² = a² + 2ab + b²

If we set a = x and b = \frac{1}{6}\right) we can see that

\left(x - \frac{1}{6}\right)^2 = x^2 - 2.x. (-\frac{1}{6}) + \frac{1}{36} = x^{2} - \frac{x}{3}+\frac{1}{36}

So

\left(x - \frac{1}{6}\right)^2=\frac{1}{4}

Taking square roots on both sides

\left(x - \frac{1}{6}\right)^2= \pm\frac{1}{4}

So the two roots or solutions of the equation are

x - \frac{1}{6}=-\sqrt{\frac{1}{4}}  and x - \frac{1}{6}=\sqrt{\frac{1}{4}}

\sqrt{\frac{1}{4}} = \frac{1}{2}

So the two roots are

x_1=\frac{1}{6} - \frac{1}{2} = -\frac{1}{3}

and

x_2=\frac{1}{6} + \frac{1}{2} = \frac{2}{3}
