- FINT THE SIDE OF THE SQUARE IF ITS AREA IS (4A2 -12AB+9B2)
2. THE PRODUCT OF TWO NUMBERS IS (X2 -13X+40)... IF ONE OF THEM IS (X-5), FIND THE OTHER
Area = 4a2 - 12 ab +9b2
=(2a)2 - 2 (2a)(3b) + (3b)2
=(2a - 3b)2
= (2a - 3b) +(2a - 3b)
We know, Area of square = Side
Side
Thus, Side of square = (2a - 3b)
=(2a)2 - 2 (2a)(3b) + (3b)2
=(2a - 3b)2
= (2a - 3b) +(2a - 3b)
We know, Area of square = Side
Side
Thus, Side of square = (2a - 3b)
