(4f-3g)(5f+6g) find the product
Answers
Answer:
20f² + 9fg - 18g
Step-by-step explanation:
The basic procedure to multiply two or more algebraic expressions is opening the brackets separately. First of all, write the first term of first bracket multiplied by the whole second bracket and then the second term of first bracket with its sign multiplied with the whole second bracket.
→ 4f(5f+6g)-3g(5f+6g)
= 20f²+ 24fg - 15fg- 18g²
= 20f² + 9fg - 18g²
20f + 9fg - 18g

→f(5f+6g)-3g(5f+6g)
= 20f²+ 24fg - 15fg- 18g?
= 20f + 9fg - 18g?
