Can you prove that:
a² + b² ≥ -2ab ?

What aspects of lines have to be diffrent

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)

Find the zeros of each function. f(x) = x^2 + 5x - 6
