8+b^2=10
b^2=2 Subtracted 8 from both sides
b=2^1/2 Took square root of both sides
b= 10
It is: 3x2+6x-11 = 0
It is a quadratic equation in the variable x.
-10 + 8 = -2

b= 10
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.
