Answer:
(2x-4i) (x+2i)
Step-by-step explanation:
2x^2+8
Factor out 2
2 ( x^2+4)
Writing as the difference of squares a^2 -b^2 = (a-b) (a+b)
2 ( x^2 -(2i)^2)
2 ( x-2i) (x+2i)
Multiplying the 2 into the first term
(2x-4i) (x+2i)
Answer: 28/125
Step-by-step explanation: To divide two fractions, flip the second fraction and multiply. The equation will be:
4/25 x 7/5
Multiply the numerators by the numerators and the denominators by the denominators.
4 x 7 = 28 (numerator)
25 x 5 = 125 (denominator)
Put into a fraction.
28/125
