Answer:
x= {2+ i}/2 , {2- i}/2 = C
Step-by-step explanation:
4x² - 8x +5 = 0
using quadratic formula
x= {-b±√b²-4ac}/2a
x= [-(-8)±√(-8)²-4(4)(5)] /2x4 = [8±√64-80]/8= [8±√-16]/8 = {8±4 i}/8
x= {8+4 i}/8 , {8-4 i}/8
x=4 {2+ i}/8 , {2- i}/8
4 divides 8
x= {2+ i}/2 , {2- i}/2 = c
Rewritten:
15w^9 - 10w^7 + 12w - 7
Leading coefficient: 15
Degree of the polynomial: 9
7 1/2 is 7.5 and 3/4 is .75, so 7.5 divided by .75 is 10.
