Simplify 4+(-3)-2x(-6)

jonny [76]

Answer:

1 + 12

Step-by-step explanation:

Let's do this one step by step!

We are going to make sure that we pay attention to the part in the parenthesis first!

Let's multiply -2x with -6 first.

Equation:

4+(-3)-2x(-6)

We do not need to parenthesis around the -3 because a negative cancels out a positive. So, no matter what you would have to subtract.

4 - 3 + 12x

And we get a positive 12 because both numbers that were being multiplied were negative.

Now let's combine common terms.

1 + 12x

This is your answer! I hope this helped!

What is the value of the discriminant of the quadratic equation −1 = 5x2 −2x, and what does its value mean about the number of r

Zepler [3.9K]

For the equation:
-1=5 x^2 - 2 x
5 x^2 - 2 x + 1 = 0, then we substitute: a=5, b=-2, c =1
to discriminant formula: D= b^2 - 4 a c = (-2)^2 - 4 * 5 * 1 = 4 - 20 = - 16
Answer:
The discriminant is equal to -16 which means the equation has no real number solutions.
