Answer:f(x)= x² + 3x + 5, depending on the interpretation of "+10 x+5."Step-by-step explanation:f(x)= x²-7x+10x+5This assume the question wants the expression simplified, which means we will combine the -7x and + 10x.f(x)= x² + 3x + 5But if the expression was meant to read f(x)= (x²-7x+10)/(x+5) the solution is slightly more complex.
