Use the babylonian method to estimate the square root of 80 to the nearest hundredth

The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b?

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol

Evaluate this using ! 0.25^2 x 2.4 + 0.25 x 2.4^2 − 0.25 x 2.4 x 0.65
