Answer:
<u>There are four different steps involved in determining extraneous solutions in any of the rational equation.</u>
Step-by-step explanation:
<u>Steps involved are:</u>
1. The very step involved is to find the "common denominator".
2. The second step includes multiplying every single thing with the "common denominator".
3. The third step includes "simplifying".
4. The last and the fourth step involves checking the answer obtained in order to assure that there's no "extraneous solution".
<u>Example of an extraneous solution in a rational equation:</u>
4÷x+3 + 7÷x²+3x = 4-x÷x
Remember revese distributeive
ab+ac=a(b+c)
factor out
(a^2)(x+3)+(-4)(x+3)
undistribute (like rreverse distribute where (x+3)=a)
(a^2-4)(x+3)
we can stil factor a^2-4 into a^2-2^2=(a-2)(a+2)
(a-2)(a+2)(x+3)
Answer:
The answer is: 3x·3x^2+3x·4+2·3x^2+2·4 APEX
Step-by-step explanation:
Answer:
(8,90°)
Step-by-step explanation:
To get this answer, you multiply the r values together to get 2*4 = 8. At the same time, you add the theta angles to get 45° + 45° = 90°
The general rule is that if A = (r,theta) and B = (s,phi) then
A*B = (r*s,theta+phi)
where the point (s,phi) is a polar form point.
