Answer:

(5x² + 3) (2x-3)

Step-by-step explanation:

10x³ - 15x² + 6x - 9 (rearrange)

10x³+ 6x - 15x² - 9 (group using parentheses)

(10x³+ 6x) - (15x² + 9) (factor out 2x from first term and 3 from second term)

2x (5x²+ 3) - 3(5x² + 3) (factor out (5x²+3) )

(5x² + 3) (2x-3) (answer)

Answer:

(15/14)² = 225/196

Step-by-step explanation:

Evaluating the expressions inside parentheses, we can see they are the same, eliminating a bit of work.

$(\frac{5}{7}\times\frac{3}{2})^5\div(\frac{5}{2}\times\frac{3}{7})^3=(\frac{15}{14})^5\div(\frac{15}{14})^3=(\frac{15}{14})^{5-3}=\boxed{(\frac{15}{14})^2=\frac{225}{196}}$
