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
Answer
6/5 and 17/8
Step-by-step explanation:
1 1/5 = 6/5
1= 5/5 + 1/5 = 6/5
2 1/8 = 17/8
2 = 16/8 + 1/8 = 17/8
Answer:
-15a^2+20ab
Step-by-step explanation:
Given data
We are given the expression
(-3a + 4b) to be multiplied by 5a
hence we have
(-3a + 4b)*5a
open bracket
-15a^2+20ab
Hence the answer is
-15a^2+20ab
