Question

multiply.
$(5c - 3)(7c - 3)$
simplify your answer.

Explanation:

Step1: Apply FOIL method

$(5c-3)(7c-3) = 5c\cdot7c + 5c\cdot(-3) + (-3)\cdot7c + (-3)\cdot(-3)$

Step2: Calculate each term

$= 35c^2 -15c -21c +9$

Step3: Combine like terms

$= 35c^2 + (-15c-21c) +9 = 35c^2 -36c +9$

Answer:

$35c^2 - 36c + 9$
