Solve the quadratic equation. Show all of your steps. x 2 + 3 x − 5 = 0
AlladinOne [14]

For this case we have the following quadratic equation:

x ^ 2 + 3x-5 = 0

Where:

a = 1\\b = 3\\c = -5

We look for the solution using the following formula:

x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}

Substituting the values:

x = \frac {-3 \pm \sqrt {3 ^ 2-4 (1) (- 5)}} {2 (1)}\\x = \frac {-3 \pm \sqrt {9 + 20}} {2}\\x = \frac {-3 \pm \sqrt {29}} {2}

Thus, we have two roots:

x_ {1} = \frac {-3+ \sqrt {29}} {2}\\x_ {2} = \frac {-3- \sqrt {29}} {2}

Answer:

x_ {1} = \frac {-3+ \sqrt {29}} {2}\\x_ {2} = \frac {-3- \sqrt {29}} {2}

Mateo has been studying after school while preparing for a test retake. His work paid off ! His score on the retake was a 94. Th
Feliz [49]

Answer:

28%

Step-by-step explanation:

We know that 100 percent is total. Mateo first scored 68/100, then a retake got his score up to 94/100.

First, subtract the two numbers

94 - 68 = 26

Put 26 over 94 to make this 26/94

Divide to get 0.28 (simplified and rounded)

So the increase was 28%
