1) Quadratic Formula is like the swiss army knife when it comes to this. Never fails, but not convenient sometimes.
2) Consider the polynomial:
x^2 + Ax + B = 0
Note that the leading coefficient is 1. Then you find two terms, say x1 and x2, whose product is B and sum is A.
Then: x^2 + Ax + B = (x-x1)(x-x2)
Sometimes, you just need a good hunting knife.
3) Consider the polynomial Ax^2 - k^2, such that A and k are real numbers.
(A^2)(x^2) - k^2 =
(Ax+k)(Ax-k)
4) Splitting the middle term.
5) Rational Root Theorem and Synthetic Division
6) Graph and approximate solutions.
This will be:
[√9]/[(3-2i)+(1+5i)]
simplifying the above we get:
√9/(3+1-2i+5i)
=√9/(4+3i)
rationalizing the denominator we get:
√9/(4-3i)×(4-3i)/(4-3i)
=[√9(4-3i)]/(16+9)
=[3(4-3i)]/25
=(12-9i)/25
Answer: (12-9i)/25
Is fry B I think I’ve had this before
2 just round up from 1.5 to 2 because it’s equal to or greater than 5 u round up
Answer:
∛49.
Step-by-step explanation:
1/2 2 and √9 ( = 3) are rational.
∛49 = 3.65930571......
- the number goes on without bounds.
