Solve 3x² + 4x = 2. (2 points)
uysha [10]

Answer:

Step-by-step explanation:

As it is a second order equation, it means that it has two possible answers and they are x_1 and x_2.

The famous quadratic formula for solving any second order equation is the following:

x_{1} = \frac{-b + \sqrt{b^2 - 4 ac}}{2a}\\x_{2}=\frac{-b - \sqrt{b^2 - 4 ac}}{2a}

Where a is the coefficient of x^2, b is the coefficient of x, and c is the free term. In other words,

a = 3\\b=4\\c=-2

as the equation should be in the following form:

a x^2 + bx+c = 0

Therefore the possible answer should be the following,

\frac{-4 + \sqrt{4^2 - 4*3*(-2)}}{2*3}=\frac{-4 +\sqrt{16 + 24}}{6} =\frac{-4 + \sqrt{40}}{6}=\\ \frac{-4 + \sqrt{4*10}}{6} = \frac{-4 + 2\sqrt{10}}{6}\frac{2*(-2 + \sqrt{10})}{2*3} = \frac{-2 + \sqrt{10}}{3}

by dividing the numerator and denominator by 2, we can deduce the following,

What is the value of p in the linear equation 24p + 12 – 18p = 10 + 2p – 6?
stira [4]

we have

24p+12-18p=10+2p-6

Group terms that contain the same variable, and move the constant to the opposite side of the equation

24p-18p-2p=10-6-12

Combine like terms

4p=-8

Divide by 4 both sides

4p/4=-8/4

p=-2

therefore

<u>the answer is</u>

the value of p in the linear equation  is -2
