Answer:

solving the equation 5x^2 - 16 = 29 we get the solution: \mathbf{x=3,x=-3}

Step-by-step explanation:

We need to solve the equation 5x^2 - 16 = 29

We need to solve the equation to find the value of x.

We can solve this equation using simple DMAS rule.

We are given:

5x^2 - 16 = 29

Add 16 on both sides

5x^2 - 16+16 = 29+16\\5x^2=45

Now, divide both sides by 5

\frac{5x^2}{5}=\frac{45}{5} \\x^2=9

Now, we know that \sqrt{x^2}=\pm x

Taking square root on both sides.

\sqrt{x^2}=\sqrt{9}\\x=\pm3

So, we get values of x:

x=3, x=-3

Therefore, solving the equation 5x^2 - 16 = 29 we get the solution: \mathbf{x=3,x=-3}
