(-8 + b2) - (5 + b2) = -8 + b2 - 5 - b2 = -13
in it's simplest form square root everything to get: a+b=8 i.e. a=8-b or b=8-a
64 plus 64 plus 64 is 192.
The equation (b2 - 2b) + (3b - 6) = b2 + b - 6
a2
A2 + B2 = C2 If C=8, then A2 + B2 = 64
(-8 + b2) - (5 + b2) = -8 + b2 - 5 - b2 = -13
24a + b2 + 3a + 2b2= 27a + 3b2
If you mean 8b+4b = 56-16b then the value of b works out as 2
in it's simplest form square root everything to get: a+b=8 i.e. a=8-b or b=8-a
64 plus 64 plus 64 is 192.
a2+2a2b+2ab2+b2
The equation (b2 - 2b) + (3b - 6) = b2 + b - 6
The polynomial IS b2 - 6b + 8.
a2
y2 - 64 can be written as y2 - 82, which is of the form of a2 - b2.And a2 - b2 is factored as (a-b)(a+b).Therefore, y2 - 64 is factored as (y+8)(y-8).
We can combine the like terms. So the b2 can be combined with the 2b2 to give 3b2. Likewise the 3b plus the -5b gives -2b.Therefore, b2 + 3b - 5b + 2b2 = 3b2 - 2b.
