Question

Find the value of q which will make the quadratic expression 9x^2-12x +q a perfect square

Answer 1

Answer:

General form of Perfect square trinomial is a2+2ab+b2. Therefore from. 16x2−bx+25. a=±4x,b=±5.

b = 40 and -40 Explanation: General form of Perfect square trinomial is a2+2ab+b2 Therefore from 16x2−bx+25 a2=√16x2,b2=25, then a=±4x,b=±5 ...
