1 + 4x = -5 + 7x
<u> -4x </u> <u> - 4x </u>
1 = -5 + 3x
<u>+5 </u> <u>+5 </u>
6 = 3x
2 = x
Answer: x = 2
Here is a quadratic equation x^2 + 5x = 14
x^2 + 5x - 14 = 0 - Subtract 14 from both sides
(x + 7)(x - 2) = 0 - Factor
x + 7 = 0 x - 2 = 0 - Set each factor equal to 0
x = -7 x = 2 - solve each piece
If the constant is easy to find factors of then use the factoring method
If the constant is difficult and you have a graphing calculator, then graph
If no graphing calculator then use the quadratic formula
answer: 6.4
work:
Solve the problem.
Let's start by solving the numerator,
(5 + 3)² <em>step one: add 5 + 3 </em>
(8)² <em>step two: simplify 8²</em>
64
now, let's simplify our denominator
1 + 2⁵ - 23 <em>step one: simplify 2⁵.</em>
1 + 32 - 23 <em>step two: add 1 + 32.</em>
33 - 23 <em>step three: subtract 33 - 23</em>
10.
now, put the numerator back over the denominator.
64/10
let's simplify by dividing, we get 6.4.

This is equal to:
When you add a negative number, it turns into subtraction.
First, I would change it to mixed numbers:
Now, you need to change the denominators to make sure they are the same on both fractions. I changed the first fraction's denominator to 4 so they match. You can do this by multiplying the numerator by 2:
Now, you simply subtract:
10-9=1
1/4 is your answer.
I hope this helps :)
