To find the value of x, we need to interpret the equation correctly. Assuming the equation is meant to represent multiplication, it should read as:
x × 5 × x = 45
We can simplify this equation step by step. Let’s rewrite it:
5x² = 45
Now, to solve for x, we first need to isolate x². We do this by dividing both sides of the equation by 5:
x² = 45 / 5
This simplifies to:
x² = 9
Next, we take the square root of both sides. Remember that squaring a number has two solutions: a positive and a negative:
x = ±√9
This gives us:
x = 3 or x = -3
Thus, the values of x that satisfy the equation are 3 and -3.
