thank you math9maniac and bobbym.
]]>Her answer although incorrect in this context is actually clever and in no way inferior to the requested answer of 50.
]]>After solving the four equations simultaneously, we have a = -10, b = 36, c = -50 and d = 25. When you substitute these values into f(x) and put f(5), the result is 50 and 5 * 0 we know is zero. There you are!
Try solving again and this should be your answer. Probably take your time with simplifying the equations.
Thanks for sharing the question. Helped me challenge myself.
]]>I am getting f(5)=50.
]]>p.s. I am getting f(5)=26 and hence the answer 2*6=12 but unfortunately it's not the correct answer.Help!
