Answer 2

To solve the equation, let's expand the product on the left side and simplify it:

(x² + 8x + 9)(x² + 8x + 5) = 63

First, we can use the distributive property to multiply the binomials:

x²(x² + 8x + 5) + 8x(x² + 8x + 5) + 9(x² + 8x + 5) = 63

Now, we can simplify each term:

x⁴ + 8x³ + 5x² + 8x³ + 64x² + 40x + 9x² + 72x + 45 = 63

Combining like terms:

x⁴ + 16x³ + 74x² + 112x + 45 = 63

Subtracting 63 from both sides:

x⁴ + 16x³ + 74x² + 112x + 45 - 63 = 0

x⁴ + 16x³ + 74x² + 112x - 18 = 0

Unfortunately, this is a quartic equation, and solving it analytically can be quite challenging. However, you can use numerical methods or graphing software to approximate the solutions.
