( 3x - 2 ) ( x² + 5x - 8 )

= 3x ( x² + 5x - 8) - 2 ( x² + 5x - 8)

= 3x³ + 15x² - 24x - 2x² - 10x + 16

= 3x³ + 13x² - 34x + 16

borishaifa [10]

Answer:

Proxima Centauri is 2.478 x 10¹³ miles from Sun.

The product fraction should be easily simplified using A and B to get the original fraction.

<em>In the case of your fraction </em> $\frac{7}{10}$ you will need to find a fraction which is a product of this: $\frac{7\timesA}{10\timesB},A=B$
