Answer:
None of the expression are equivalent to 
Step-by-step explanation:
Given

Required
Find its equivalents
We start by expanding the given expression

Expand 49


Using laws of indices: 


This implies that; each of the following options A,B and C must be equivalent to
or alternatively, 
A. 
Using law of indices which states;

Applying this law to the numerator; we have

Expand expression in bracket


Also; Using law of indices which states;

becomes

This is not equivalent to 
B. 
Expand numerator


Using law of indices which states;

Applying this law to the numerator; we have


Also; Using law of indices which states;

= 
This is also not equivalent to 
C. 



Using law of indices which states;


This is also not equivalent to 
Answer:you just find the answer from the 2 fractions you have
Step-by-step explanation:
Answer: If the quadratic equation has real, rational solutions, the quickest way to solve it is often to factorise into the form (px + q)(mx + n), where m, n, p and q are integers. This is especially true where the coefficient of x2 is 1.
Example 1 - Solve x2+7x+12=0
Step-by-step explanation:
that's the only one I remember
