It is -2. This is negative. For instance, if you had 3 candies and your mother took away 5, you would not only have 0 candies, but you would owe your mother 2. This is expressed as a negative number. Please mark Brainliest!!!

The answer is -2.
Think of it as counting down when I’m the negative. Like the 3 + (-5). (-5)+1 is -4. So 3+(-5)=-2

Answer and Step-by-step explanation:

$\pi$ is pi, or 3.14159

The absolute value of -4 ( |-4| ) is 4.

These numbers should go in this order:

-10 < 0.121212... < $\pi$ < |-4| < $5\frac{1}{2}$

Have a good day!

Select the two values of x that are roots of this equation 3x^2 + 1 =5x

Zina [86]

Answer:

x = 1.434 and x=0.232

Step-by-step explanation:

To find the root of the equation stated above we need to:

(1) Write the polynomial equation with zero on the right hand side:

$3x^{2} + 1 = 5x$ ⇒ $3x^{2} -5x + 1 = 0$

(2) Divide the whole equation by 3

$3x^{2} -5x + 1 = 0$ ⇒ $x^{2} -\frac{5}{3}x + \frac{1}{3}= 0$

(3) Use the quadratic formula to solve the quadratic equation:

The quadratic formula states that the two solutions for a quadratic equation is given by:

$\frac{-b±\sqrt{b^{2} - 4ac}}{2a}$ (1)

In this case, a = 1, b = $-\frac{5}{3}, c= \frac{1}{3}$

Substituiting a, b and c in equation (1) We get:

$\frac{-\frac{5}{3}±\sqrt{(-\frac{5}{3})^{2} - 4(1)(\frac{1}{3})}}{2(1)}$ (1)

The two solutions are:

x = 1.434 and x=0.232
