Answer:
2 ± i
Step-by-step explanation:
by 5, I assume you mean +5
x² - 4x + 5 = 0
x = (-b±(√(b²-4ac)) / 2a
x = (4 ± (√(16 - 20)) / 2
x = (4 ± (√(-4)) / 2
√-4 = √4√-1 which is 2i
x = (4 ± 2i) / 2
x = 2 ± i
Answer:
7=x
Step-by-step explanation:
2x+34=4(x+5)
2x+34=4x+20
-2x -2x
34=2x+20
-20 -20
14=2x
/2 /2
