Solve for [tex]\( x \)[/tex]:

[tex]\[ 4x^2 + 72 = 6x^2 \][/tex]


Sagot :

Certainly! Let's solve the equation step-by-step together:

The given equation is:

[tex]\[ 4x^2 + 72 = 6x^2 \][/tex]

Step 1: Move all terms to one side of the equation.

We need to move all the terms involving [tex]\(x\)[/tex] to one side of the equation and constants to the other side. In this case, we can subtract [tex]\(4x^2\)[/tex] from both sides:

[tex]\[ 4x^2 + 72 - 4x^2 = 6x^2 - 4x^2 \][/tex]

Simplifying this, we get:

[tex]\[ 72 = 2x^2 \][/tex]

Step 2: Isolate the term involving [tex]\(x^2\)[/tex].

Next, we divide both sides of the equation by 2 to isolate [tex]\(x^2\)[/tex]:

[tex]\[ \frac{72}{2} = x^2 \][/tex]

Simplifying this, we obtain:

[tex]\[ 36 = x^2 \][/tex]

Step 3: Solve for [tex]\(x\)[/tex].

Now, we need to find the value(s) of [tex]\(x\)[/tex] that satisfy [tex]\(x^2 = 36\)[/tex]. To do this, we take the square root of both sides:

[tex]\[ x = \pm\sqrt{36} \][/tex]

Evaluating the square root, we get:

[tex]\[ x = \pm 6 \][/tex]

Thus, the solutions to the equation [tex]\(4x^2 + 72 = 6x^2\)[/tex] are:

[tex]\[ x = 6 \text{ and } x = -6 \][/tex]
