Hi there

(x² + 7x + 12) (x² + 3x + 5)

Distribute

(x²) (x²) + (x²) (3x) + (x²) (5) + (7x) (x²) + (7x) (3x) + (7x) (5) + (12) (x²) + (12) (3x) + (12) (5)

= x^4 + 3x^3 + 5x^2 + 7x^3 + 21x^2 + 35x + 12x^2 + 36x + 60

= x^4 + 10x^3 + 38x^2 + 71x + 60

Good luck!

A small simplification is (9x + 12) (5x + 5), or it would be 45x+17.
