# Determine whether the statement is true or false. If it is true, explain why. If it is false, explain why or give an example that disproves the statement. x 2 − 4 x ( x 2 + 4 ) can be put in the form A x + B x 2 + 4 .

To determine

To Discuss: If x24x(x2+4)=Ax+Bx2+4 is true or false

Explanation

The degree of the numerator is less than the degree of denominator in the expression x24x(x2+4) where one of the factors is linear and the other one is quadratic which further cannot be factorized. So, using the concept of partial fraction
