Julie wants to factorize the following trinomial x² + 9x + 20 provide her 3 easy steps to follow ?

Step 1: Identify the coefficients of the trinomial. In this case, the coefficients are a = 1, b = 9, and c = 20.

Step 2: Find two numbers that multiply to a*c (1*20 = 20) and add up to b (9). In this case, the numbers are 4 and 5 because 4*5 = 20 and 4+5 = 9.

Step 3: Rewrite the trinomial using the two numbers found in step 2. The factored form of x² + 9x + 20 is (x + 4)(x + 5).

Step 1: Find two numbers that multiply to 20 and add to 9.

- The two numbers are 4 and 5, since 4 - 5 = 20 and 4 + 5 = 9.

Step 2: Rewrite the middle term using the two numbers found in Step 1.

- x² + 4x + 5x + 20

Step 3: Factor by grouping.

- (x² + 4x) + (5x + 20)
- x(x + 4) + 5(x + 4)
- (x + 4)(x + 5)
