Question

(5a square +6b square) whole square

Answer 1

Step-by-step explanation:

Simplifying

b(15 + -3b)(15 + 5b)

Multiply (15 + -3b) * (15 + 5b)

b(15(15 + 5b) + -3b * (15 + 5b))

b((15 * 15 + 5b * 15) + -3b * (15 + 5b))

b((225 + 75b) + -3b * (15 + 5b))

b(225 + 75b + (15 * -3b + 5b * -3b))

b(225 + 75b + (-45b + -15b2))

Combine like terms: 75b + -45b = 30b

b(225 + 30b + -15b2)

(225 * b + 30b * b + -15b2 * b)

(225b + 30b2 + -15b3)
