Answer:
3k² + k - 10
Step-by-step explanation:
Given
(3k - 5)(k + 2)
Each term in the second factor is multiplied by each term in the first factor, that is
3k(k + 2) - 5(k + 2) ← expand both parenthesis
= 3k² + 6k - 5k - 10 ← collect like terms
= 3k² + k - 10 ← in expanded form
Answer:
3k² + k - 10
Step-by-step explanation:
[tex]\text{Use FOIL:}\ (a+b)(c+d)=ac+ad+bc+bd\\\\(3k-5)(k+2)\\\\=(3k)(k)+(3k)(2)+(-5)(k)+(-5)(2)\\\\=3k^2+6k-5k-10\qquad\text{combine like terms}\\\\=3k^2+(6k-5k)-10\\\\=3k^2+k-10[/tex]
