Determine which of the given values of [tex]\(x\)[/tex] are the roots of [tex]\(4x(x-3) = 2x + 6\)[/tex].

Given values:
[tex]\[ x = 3, \quad x = 0, \quad x = 2 \][/tex]


Sagot :

We need to determine which of the given values of [tex]\( x \)[/tex] are the roots of the equation [tex]\( 4x(x - 3) = 2x + 6 \)[/tex]. The values of [tex]\( x \)[/tex] to test are 3, 0, and 2.

The first step is to rewrite the given equation in standard quadratic form.

### Step 1: Rewrite the equation
Starting with the provided equation:
[tex]\[ 4x(x - 3) = 2x + 6 \][/tex]

Distribute the [tex]\( 4x \)[/tex] on the left-hand side:
[tex]\[ 4x^2 - 12x = 2x + 6 \][/tex]

Next, bring all terms to one side of the equation to set it to zero:
[tex]\[ 4x^2 - 12x - 2x - 6 = 0 \][/tex]

Combine like terms:
[tex]\[ 4x^2 - 14x - 6 = 0 \][/tex]

We now have the quadratic equation:
[tex]\[ 4x^2 - 14x - 6 = 0 \][/tex]

### Step 2: Test the given values
We test each value of [tex]\( x \)[/tex] by substituting them into the quadratic equation and checking if they satisfy the equation.

#### Test [tex]\( x = 3 \)[/tex]:
[tex]\[ 4(3)^2 - 14(3) - 6 = 0 \][/tex]
[tex]\[ 4(9) - 42 - 6 = 0 \][/tex]
[tex]\[ 36 - 42 - 6 = 0 \][/tex]
[tex]\[ -12 \neq 0 \][/tex]

So, [tex]\( x = 3 \)[/tex] is not a root.

#### Test [tex]\( x = 0 \)[/tex]:
[tex]\[ 4(0)^2 - 14(0) - 6 = 0 \][/tex]
[tex]\[ 4(0) - 14(0) - 6 = 0 \][/tex]
[tex]\[ 0 - 6 = 0 \][/tex]
[tex]\[ -6 \neq 0 \][/tex]

So, [tex]\( x = 0 \)[/tex] is not a root.

#### Test [tex]\( x = 2 \)[/tex]:
[tex]\[ 4(2)^2 - 14(2) - 6 = 0 \][/tex]
[tex]\[ 4(4) - 14(2) - 6 = 0 \][/tex]
[tex]\[ 16 - 28 - 6 = 0 \][/tex]
[tex]\[ -18 \neq 0 \][/tex]

So, [tex]\( x = 2 \)[/tex] is not a root.

### Conclusion
None of the given values [tex]\( x = 3 \)[/tex], [tex]\( x = 0 \)[/tex], or [tex]\( x = 2 \)[/tex] are roots of the equation [tex]\( 4x(x - 3) = 2x + 6 \)[/tex].

Thus, the determined roots from the given values are:
[tex]\[ \boxed{[]} \][/tex]
There are no values among 3, 0, and 2 that satisfy the equation.
