If (4a + 7b) (4c – 7d) = (4a – 7b) (4c + 7d), then which one of the following is correct?Options𝒂/𝒃=𝒄/𝒅𝒂/𝒃=𝒅/𝒄𝟒𝒂/𝟕𝒃=𝒄/𝒅𝒂/𝒅=𝒄/𝒃
Question
Solution 1
Let's expand both sides of the equation:
Left side: (4a + 7b) (4c – 7d) = 16ac - 28ad + 28bc - 49bd
Right side: (4a – 7b) (4c + 7d) = 16ac + 28ad - 28bc + 49bd
Setting the left side equal to the right side gives us:
16ac - 28ad + 28bc - 49bd = 16ac + 28ad - 28bc + 49bd
