Answer:

This equation does not have a solution.

If you subtract 5 from both sides of the equation, you will get 6x-10 = 6x. Then if you subtract 6x from both sides, you will end up with -10 = 0 which is untrue. Therefore, the equation 6x-5 = 6x+5 has no solution.

Answer:

$\frac{4+16a^3+23a^3}{a^2}$

Step-by-step explanation:

Given

$1/a^2-3a+2 + 1/a^2-5a+6 + 2/a^2-8a+15$

Required

Simplify

$1/a^2-3a+2 + 1/a^2-5a+6 + 2/a^2-8a+15$

Collect Like Terms

$1/a^2 + 1/a^2 + 2/a^2-3a-5a-8a+2+6+15$

$1/a^2 + 1/a^2 + 2/a^2-16a+23$

Add Fractions:

$\frac{1+1+2}{a^2} + 16a + 23$

$\frac{4}{a^2} + 16a + 23$

This can be further expressed as:

$\frac{4+16a^3+23a^3}{a^2}$
