Answer:

a.)

Step-by-step explanation:

(\sqrt{12}+6)(-\sqrt{8}-\sqrt{2})

Find the simplest radical form for \sqrt{12}:

Find two numbers that multiply to 12, one of which is a perfect square:

\sqrt{12}=\sqrt{3*4}

Separate:

\sqrt{3}\sqrt{4}

Simplify by finding the square root:

\sqrt{3}*2=2\sqrt{3}

Insert the simplified version:

(2\sqrt{3}+6)(-\sqrt{8}-\sqrt{2})

Find the simplest radical form of \sqrt{8}:

Find two numbers that multiply to 8, one of which is a perfect square:

\sqrt{8}=\sqrt{4*2}

Separate:

\sqrt{4} \sqrt{2}

Simplify by finding the square root:

2\sqrt{2}

Insert the simplified version:

(2\sqrt{3}+6)(- 2\sqrt{2}-\sqrt{2})

Calculate 6+9i/-1+4i
lisabon 2012 [21]

Multiply the numerator and denominator by the conjugate of the denominator:

\dfrac{6+9i}{-1+4i} \times \dfrac{-1-4i}{-1-4i} = \dfrac{(6+9i)(-1-4i)}{(-1)^2-(4i)^2}

Simplify:

\dfrac{(6+9i)(-1-4i)}{(-1)^2-(4i)^2} = \dfrac{-6-9i-24i-36i^2}{1-16i^2} = \dfrac{-6-33i-36i^2}{1-16i^2} = \dfrac{-6-33i+36}{1+16} = \boxed{\dfrac{30-33i}{17}}
