Answer:

$P(x)=-2x^2+28x-66$

Step-by-step explanation:

$P(x)=-2(x-3)(x-11)\\\\P(x)=-2(x^2-3x-11x+33)\ \ \ \ \ \ multiplication\ of\ (x-3)\ and\ (x-11)\\\\P(x)=-2(x^2-14x+33)\ \ \ \ \ \ \ distributive\ property\\\\P(x)=-2x^2+28x-66$

How do I simplify this (sinx)/(secx+1)

pochemuha

Answer:

Step-by-step explanation:

$\frac{sin~x}{sec~x+1} =\frac{sin~x}{\frac{1}{cos~x}+1 } =\frac{sin~x~cos~x}{1+cos~x} \\=\frac{sin~x~cos~x}{1+cos~x} \times \frac{1-cos~x}{1-cos~x} \\=\frac{sin~x~cos~x(1-cos~x)}{1-cos^2 x} \\=\frac{sin~x~cos~x(1-cos~x)}{sin^2x} \\=\frac{cos~x(1-cos~x)}{sin~x} \\=cos ~x(csc~x-cot~x)\\or\\=cot~x(1-cos~x)$
