Final answer:

To solve the equation 7ax³ + 5ax + 1 = 52, you can rearrange it to set it equal to zero. Then factor out a common factor of ax and set each factor equal to zero. By solving these equations, you will find the solutions to the equation.

Step-by-step explanation:

To solve the equation 7ax³ + 5ax + 1 = 52, we first need to rearrange it so that it is equal to zero.

7ax³ + 5ax + 1 - 52 = 0

Simplifying further:

7ax³ + 5ax - 51 = 0

Now, we can solve this equation either by factoring or by using the quadratic formula. In this case, factoring seems the more appropriate method.

Let's factor out a common factor of ax:

ax(7x² + 5) - 51 = 0

Now, we have two factors: ax and (7x² + 5).

We can set each factor equal to zero:

ax = 0

7x² + 5 = 0

Solving the first equation:

ax = 0

Since a is not equal to zero, we can divide both sides by a:

x = 0

Now, solving the second equation:

7x² + 5 = 0

Subtracting 5 from both sides:

7x² = -5

Dividing both sides by 7:

x² = -5/7

Taking the square root of both sides:

x = ±√(-5/7)

Therefore, the solutions to the equation are x = 0 and x = ±√(-5/7).
