Q2 of 227 Page 101

Find the values of a and b if the following polynomials are perfect squares.

4x4–12 x3 + 37x2 + ax + b

Step 1: Find the algebraic expression whose square gives the first term.


Step 2: Add the divisor and quotient .To this sum add a suitable expression and add the same expression in the quotient such that the product gives the next term.


Step 3: Continue the process until all the terms are divided.
