Lie is solving the quadratic equation by completing the square. 3x2 + 18x – 8 = 0 3x2 + 18x = 8 what should lie do next?

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

Factor x2 – 8x + 15. which pair of numbers has a product of ac and a sum of what is the factored form of the

The distributive property allows you to say that 3(x − 1) = 3x −
