Answer 3

To solve the equation 6 - 5x(4x - 1) = 3, we'll follow the order of operations (also known as PEMDAS: Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

First, let's simplify the expression within the parentheses:

4x - 1

Next, let's apply the distributive property by multiplying -5x with each term inside the parentheses:

-5x * 4x = -20x^2 -5x * -1 = 5x

Now the equation becomes:

6 - 20x^2 + 5x = 3

We can rearrange the equation to put it in the standard quadratic form (ax^2 + bx + c = 0):

-20x^2 + 5x + 6 - 3 = 0

Simplifying further:

-20x^2 + 5x + 3 = 0

To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. However, upon inspecting the equation, it doesn't appear to factor easily, so we'll use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

For our equation, a = -20, b = 5, and c = 3. Substituting these values into the quadratic formula:

x = (-5 ± √(5^2 - 4(-20)(3))) / (2(-20)) x = (-5 ± √(25 + 240)) / (-40) x = (-5 ± √265) / (-40)

At this point, we have two potential solutions:

x₁ = (-5 + √265) / (-40) x₂ = (-5 - √265) / (-40)

These are the solutions to the given equation.
