Question

(2j+2)(j-1)
multiply two binomials​

Answer 1

2j^2 - 2

Explanation:

1. Apply the FOIL method to the equation:

(a + b) (c + d) => (2j + 2) (j - 1)

2. Distribute by using the formula: (ac +ad + bc + bd)

2j x j = 2j^2, 2j x -1 = -2j, j x 2 = 2j, 2 x -1 = -2.

3. Combine like terms: 2j^2 + 2j + -2j = 2j^2

4. SOLUTION: 2j^2 + 2
