Can someone help me solving this equation for x please

Mathematics
1 answer:
torisob [31]3 years ago
6 0

Answer:

  ±2/11

Step-by-step explanation:

Take the square root of both sides of the equation:

  \sqrt{x^2}=\sqrt{\dfrac{4}{121}}\\\\\boxed{x=\pm\dfrac{2}{11}}

_____

Here, we need to recognize that (-2/11)^2 = (2/11)^2 = 4/121, so both the positive and negative roots of 4/121 are solutions to the equation.

pantera1 [17]
Alright. -2-(-4) = -2 + 4 because a negative and a negative equals to a positive[(-2-(-4)]. It would look like: Put a dot on -2, then move your dot 4 units to the right, which is +2.

Find the difference of(ab+8a+1)-(-6ab+4)
vagabundo [1.1K]
Hey there!

When finding the difference of expressions like these, there's a few things you should keep in mind. 

1. When finding the difference of two polynomials, multiply the polynomial that implied to be "negative" by –1 to expand the problem and make it easier to solve. 

2. You combine terms based on their unknown terms, like x, y, x², ab, etc. You cannot combine the terms x and x², but you can combine the terms 6b and 8b by adding them. 

3. You can rearrange your terms however you see fit. If a polynomial is implied as "positive", you can multiply that entire polynomial by +1 to get rid of the parentheses. 

With all that in mind, you can go ahead and solve for your difference, like so:

(ab+8a+1)-(-6ab+4)

(ab+8a+1) (-1(-6ab+4))

(ab+8a+1) + (6ab-4)

ab+6ab+8a+1-4

7ab+8a-3

7ab+8a-3 will be your difference. 

Hope this helped you out! :-)
