To factorize the quadratic expression 5x²+9x+4, we need to find two numbers that multiply to 5⋅4=20 (the product of the coefficient of x² and the constant term) and add up to 9 (the coefficient of x).

Let's find the factors of 20 that add up to 9:

The factors of 20 are 4 and 5.

Therefore, we can factor x²+9x+4 as: (5x+4)(x+1)
