How many different ways can you solve a quadratic equation? List them.

Mathematics

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.

Answer:

$3.98(estimated)

Step-by-step explanation:

3c (cake) + 2(2c - 11) (bread) = 5.87

3c + 4c - 22 = 5.87

7c - 22 = 5.87

7c = 5.87 + 22

7c = 27.87

c = 3.98

You increase the size of a page by 30%. Then you decrease it by 30%. What is the size of the page now?
kotegsom [21]
Lets use 1 to solve this problem because it is easiest to show. 

Multiply 1 by 1.3 for a 30% increase (1*1.3=1.3). 

Then multiply 1.3 by .7 for a 30% decrease. (1.3*.7=.91)  

Therefore the page had a 9% reduction from its original size or is 91% of its original size.

You are choosing between two health clubs. Club A offers membership for a fee of $12 plus a monthly fee of $28. Club B offers me
EleoNora [17]

A has fixed one time fee of $12 and if you go to it say "m" months you pay $28 for each month, so your total cost at A is really 12 + 28m.

B has a fixed one time fee of $20 and if you go to it "m" months you pay $26 for each month, so you total cost at B is 20 + 26m.

how many months for the cost to be the same?

\stackrel{A}{12+28m}=\stackrel{B}{20+26m}\implies 12+2m=20\implies 2m=8\implies m=\cfrac{8}{2}\implies m=4

well, since the cost for both is the same, we can just get A's, knowing that B is the same

12+28(4)\implies 12+112\implies 124

Best explained/correct answer gets brainliest.
Nuetrik [128]
3, 15, 75, 375, and here's why:
Basically, it's asking you to take 3, and multiply it by five each time to get a pattern.

1: 3
2: 
3*5 = 15
3: 
15*5 = 75
4: 
75*5 = 375

Add these together: 
3 + 15 + 75 + 375 = 468

Your answer is "A)", 468.

Answer: Non-Linear Function line

Step-by-step explanation:

The reason is if it was a linear one then it would be a straight line and since this is not a straight line then it is a Non-Linear Function because you can't just look at it and see what the increase and decrease was for a certain time period.
