Answer:
a) 78
b) 1275.....
Step-by-step explanation:
.............
[(18x - 6) / 9x^5] / [(15x + 5) / 21x^2]
<span>The initial equation formulated would be:
[6(3x - 1) / 9x^5][21x^2 / 5(3x + 1)] </span>
By simplifying:
[126x^2(3x - 1) / [45x^5(3x + 1)]
14(3x - 1) / 5x^3(3x + 1)
<span>Therefore, the simplest form would be:
(42x - 14) / (15x^4 + 5x^3)
