Answer:

x=0,-1 and x=

x=\frac{2+\sqrt{10}}{3},\frac{2-\sqrt{10}}{3}x=

Step-by-step explanation:

1 Cancel 2 on both sides.

3{x}^{2}+3x=03x

+3x=0

2 Factor out the common term 3x3x.

3x(x+1)=03x(x+1)=0

3 Solve for xx.

x=0,-1x=0,−1

1 Move all terms to one side.

3{x}^{2}-3x-1-x-1=03x

−3x−1−x−1=0

2 Simplify 3{x}^{2}-3x-1-x-13x

−3x−1−x−1 to 3{x}^{2}-4x-23x

−4x−2.

3{x}^{2}-4x-2=03x

−4x−2=0

3 Use the Quadratic Formula.

x=\frac{4+2\sqrt{10}}{6},\frac{4-2\sqrt{10}}{6}x=

4+2√

4−2√

4 Simplify solutions.

x=\frac{2+\sqrt{10}}{3},\frac{2-\sqrt{10}}{3}x=

2+√

2−√

Multiply and and simplify : (a+b)^2 Pls help easy

Lena [83]

Answer:a^2+2ab+b^2

Step-by-step explanation:

First write it out in extended form, (a+b)(a+b) then multiply each term by the other in each parenthesis, such as a*a+b*b+a*b+a*b

Then, once you have done that, simplify it. you will then get the answer a^2+2ab+b^2

The graph of y=x^2 was transformed to Y= -(x+3)^2 +5. Describe all transformations applied to the original function and determin

mina [271]

Hey there!

1. The graph was flipped vertically and now opens downward.

We know this because there is a negative sign in front of the equation:

$y=$ $\boxed-$ $(x+3)^2+5$

2. The graph was moved 3 units to the left.

We know this because there is 3 added to x inside of the parenthesis. Remember, inside (parenthesis) is opposite and acts on x, outside (parenthesis) is same and acts on y.

$y=-(x\boxed{+3})^2+5$

3. The graph was moved 5 units up.

We know this because there is 5 added at the end of the equation. It acts on y because it is outside of the parenthesis.

$y=-(x+3)^2\boxed{+5}$

Hope this helps!

What is the union sets M= (1,7,10,11,15) and N=(5,15)?

katen-ka-za [31]

Answer: (1,5,7,10,11,15)

To get the union of two sets of numbers, all you do is combine the numbers from least to greatest. If a number repeats in the 2 sets, you only put it once.
