Expand (6 + 5a)(7 - 5b)

Step 1: Multiply (6 + 5a) * (7 - 5b)

Note: This is a special expansion which uses FOIL: (First-Outside-Inside-Last)

Step 1.1: Multiply 6 by each term in 7 - 5b

Step 1.1.1: Multiply 6 * 7

(6 * 7)

42

Step 1.1.2: Multiply 6 * -5b

(6 * -5)(b

-30b

Step 1.2: Multiply 5a by each term in 7 - 5b

Step 1.2.1: Multiply 5a * 7

(5 * 7)(a

35a

Step 1.2.2: Multiply 5a * -5b

(5 * -5)(a

-25ab

Step 1 answer = 42 - 30b + 35a - 25ab

42 - 30b + 35a - 25ab
