It is 44. Just insert the 6 where -x is, and it would look like this: -62 +8, 36+8= 44. And this is easy. I did this all in my head, and Im only an 8th Grader.
It is actually read as the opposite of x squared plus six and would look like this:
-62= -36+8=-28 Because of order of operations you have to square six before applying the negative.
b= 10
It is: 3x2+6x-11 = 0

It is a quadratic equation in the variable x.

To calculate 6 squared plus 8 squared, you first need to square each number individually. 6 squared is 6 x 6, which equals 36. 8 squared is 8 x 8, which equals 64. Adding these two results together, you get 36 + 64, which equals 100. So, 6 squared plus 8 squared is 100.
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.

It is: 3x2+6x-11 = 0
6 plus 7 plus 8 equals 6 plus 8 plus 7, what property is that?That is the associative property.

8 + X SQUARED
A squared = 6x6 = 36 B squared = 8x8 = 64 Square root of 36+64 = 10 Given: a2 + b2 = c2 a = 6 and b = 8. We need to find the value of c. a = 6 implies a2 = 62 = (6*6) = 36. b = 8 implies b2 = 82 = (8*8) = 64. a2 + b2 = c2 implies 62 + 82 = c2 c2 = 36 + 64 c2 = 100 c2 = 102 c = 10
