It is equivalent too 5.3 and 5.30
Answer: 12p^3r and 54p^3
Step-by-step explanation:
Only add 1 and 5 first, then your denominator would be 32 because 8 times 4 is 32.
The first thing to remember is that when you have a zero of 3i, you will also have a zero of -3i. This is because of the way imaginary solutions are created (taking the square root of a negative number). When you take the sqrt you get TWO answers.
The factors for these zeros are (x - 3i)(x+3i)(x+2)(x-1)
When you multiply the factors, the polynomial will be:
x^4 + x^3 + 7x^2 + 9x - 18
