Answer:

Step-by-step explanation:
If we have an equation
and we want to find what b is in relation to a, we can change the equation so that we have b on one side and whatever is on the other side is what b is.

To isolate b, we can take the square root of both sides as taking the square root of something squared results in the base.


So b is the square root of a.
Hope this helped!
Answer:
(11b^2 + 7) (11b^2 - 7)
Explanation:
Since both terms are perfect squares, factor using the difference of squares formula, a^2 - b^2 = (a + b) (a - b) where a = 121b^4 and b = 49
Answer:
Step-by-step explanation:12x2 + 3x + 6 + (-7)x2 - 4x - 2 = 0
12•x•2 + 3•x + 6 + (-7)•x•2 - 4•x - 2 = 0
9x = -4
x = -4/
