Find a degree 3 polynomial with real coefficients having zeros 4 and 4i and a lead coefficient of 1. Write P in expanded form.

The answer would be 2 times 3 plus 8 divided by 8 = 7

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.

Let smaller number be 2x , then the nest even number will be 2x + 2so   2x + 4(2x + 2) = 582x + 8x + 8 = 5810x = 50x = 5  so the first number is 2*5   = 10 and second one is 12
