What are the solutions of x2 + 10x + 16 = 0?
1. Write the equation in standard form.
2. Factor the polynomial.
3. Apply the zero product property.
4. Solve the resulting equations.
x2 + 10x + 16 = 0
(x + 2)(x + 8) = 0
x + 2 = 0 or x+8 = 0
and x = And x=

(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.

A. 127 cm^2 b. 144.5 cm^2 c. 172 cm^2 d. 50 cm^2
