Digiron [165]3 years ago
8 0

Solution :

GIven equation \frac{1}{3} x (15x-12y)-\frac{1}{2} (6x-4y)

To simplify this equation , we first evaluate the terms in bracket

= \frac{1}{3} x (15x) -\frac{1}{3} x(12y) -\frac{1}{2} (6x)+\frac{1}{2} (4y)
\\
= 5x^2-4xy-3x+2y

Hence,  \frac{1}{3} x (15x-12y)-\frac{1}{2} (6x-4y) = 5x^2-4xy-3x+2y
