Find the values of a and b if the following polynomials are perfect squares, By equating the coefficients of x, we get. Syllabus. Hence the square root of x4 â12x3 + 42x2 â36x + 9 is x2 - 6x + 3. First let us arrange the given polynomial from greatest order to least order. If the number of digits in it is odd, then the left-most single digit too will have a bar.Thus we have, 7 29.So 1st bar is on 29 and 2nd bar is on 7. By dividing -12x3 by 2x2, we get -6x. Step 2 : Multiplying the quotient (x 2) by 2, so we get 2x 2.Now bring down the next two terms -12x 3 and 42x 2.. By dividing -12x 3 by 2x 2, we get -6x. For example, the square root of 16 is 4, because 16 is a perfect square of 4, such as: 4 2 = 16 and √16 = 4.
