3+-√(-3)^2 - 4(5)(-1)

Alona [7]

Answer:

Step-by-step explanation:

Easy way to do this is step by step. Your quadratic, from your entry, must be

$5x^2-3x-1$ .

Step by step looks like this, one thing at a time:

$x=\frac{3+\sqrt{(-3)^2-4(5)(-1)} }{2(5)}$ becomes

$x=\frac{3+\sqrt{9-(-20)} }{10}$ becomes

$x=\frac{3+\sqrt{9+20} }{10}$

and this of course is

$x=\frac{3+\sqrt{29} }{10}$

Do the same with the subtraction sign to get the other solution.

If you're unsure of how to enter it into your calculator, do it step by step so you don't mess up the sign. If you enter it incorrectly, you could end up with an imaginary number when it should be real, or a real one that should be imaginary.

Just my advice as a high school math teacher.

What is the solution to 4 ***25-79 ΧΣ- 12 ΧΣ 12 Ο χK12 Ο χ4 - 12

jekas [21]

Answer:

$\displaystyle x \leq 12$

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtraction Property of Equality

Step-by-step explanation:

Step 1: Define

$\displaystyle -\frac{3}{4}x + 2 \leq -7$

Step 2: Solve for x

[Subtraction Property of Equality] Isolate x term: $\displaystyle -\frac{3}{4}x \leq -9$
[Division Property of Equality] Isolate x: $\displaystyle x \leq 12$

Here we see that any value x smaller than or equal to 12 would work as a solution to the inequality.
