Answer:

Step-by-step explanation:

factor the coefficients into primes

18 = 3 *<u> 3 * 2</u>

42 <u>= 3* 2</u> * 7

- 12 = - 2 * <u>2 * 3</u>

The primes that are underlined are 2 * 3 which is 6

The primes not in the brackets are what is inside the brackets.

6(3x^2 + 7x - 2)

tia_tia [17]

Answer:

=45x√5x

Step-by-step explanation:

The provided expression is: 3√5x×3√25x²

We can simplify 3√25x² because √25x²=5x

3×5x=15x

Combine with the rest of the expression through multiplication.

3√5x×15x

=45x√5x

The expression 3√5x×3√25x² is equivalent to 45x√5x.

The expected simplified answer is 45x√5x

siniylev [52]

Answer:

\frac{2}{a}

Step-by-step explanation:

Given

\frac{6-12b}{3a-6ab} ← factor both numerator and denominator

= \frac{6(1-2b)}{3a(1-2b)} ← cancel common factor (1 - 2b) on numerator/denominator

= \frac{6}{3a} ← cancel 6 and 3 by 3

= \frac{2}{a}
