Which of the following is a valid exclusion for the algebraic fraction 8ab^2x/4a^2b-8ab^2

Molodets [167]

Answer:

a ≠ 2b

Step-by-step explanation:

The given expression is

$\frac{8ab^{2}x}{4a^{2}b-8ab^{2}}$

$=\frac{8ab^{2}x}{4ab(a-2b)}$

Simplifying it, we have

$\frac{8ab^{2}x}{4a^{2}b-8ab^{2}} = \frac{bx}{a-2b}$

For the above fraction to exist, the denominator must not be equal to zero.

i.e, a-2b ≠ 0

=> a≠2b

∴ The algebraic fraction exists when a≠2b.

2. Find the bigger solution of the equation x2 - 11x = 0.

pickupchik [31]

Answer:

$x\text{ = 11}$

Explanation:

Here, we want to find the bigger solution

We can start by factoring x as follows:

$\begin{gathered} x(x-11_)\text{ = 0} \\ x\text{ = 0 or x-11 = 0} \\ x\text{ = 0 or x = 11} \end{gathered}$

The bigger solution is x= 11
