Question

(b-3)(b-5)
answer it step by step​

Answer 1

Answer:

1

Distribute

(−3)(−5)

{\color{#c92786}{(b-3)(b-5)}}(b−3)(b−5)

(−5)−3(−5)

{\color{#c92786}{b(b-5)-3(b-5)}}b(b−5)−3(b−5)

2

Distribute

(−5)−3(−5)

{\color{#c92786}{b(b-5)}}-3(b-5)b(b−5)−3(b−5)

2−5−3(−5)

{\color{#c92786}{b^{2}-5b}}-3(b-5)b2−5b−3(b−5)

3

Distribute

2−5−3(−5)

b^{2}-5b{\color{#c92786}{-3(b-5)}}b2−5b−3(b−5)

2−5−3+15

b^{2}-5b{\color{#c92786}{-3b+15}}b2−5b−3b+15

4

Combine like terms

2−5−3+15

b^{2}{\color{#c92786}{-5b}}{\color{#c92786}{-3b}}+15b2−5b−3b+15

2−8+15
