Answer:
w^2 + 13w + 39
Step-by-step explanation:
Multiplying Polynomials (FOIL- Firsts, Outs, Inners, Lasts)
(w+9) (w+4) Multiply- Firsts (w*w) Outs (w*4) Inners (9*w) Lasts (9*4)
w*w + w*4 + 9*w + 9*4 Multiply the FOIL
w^2 + 4w + 9w + 36 Combine like terms (same variables, numbers)
w^2 + 13w + 39
Answer:
a
Step-by-step explanation:
Answer:
(d) f(x) = (x − 3)^2(x − 2)(x − 1)
Step-by-step explanation:
In this context, a crossing of the axis at x=p means there is a factor of (x-p). A "touch" of the axis at x=q means there is a factor of (x -q)^2.
A crossing at x=1 and x=2, and a touch at x=3 means the factors are ...
f(x) = (x -1)(x -2)(x -3)^2 . . . . . matches the last choice
Step-by-step explanation:
You find the complex conjugate simply by changing the sign of the imaginary part of the complex number.
the answer is
9+3i
