N = {15 +- root of ( 225 + 64) } / 2
= {15 +- root of 289 } / 24
= 15 + 17 } / 2 or { 15 -17 } /2
= 16 or -1
Answer:
-5(1-I) is the answer
Step-by-step explanation:
(1+2i)(1+3i)
1(1+3i)+2i(1+3i)
1+3i+2i+6i^2
As i^2=-1
1+5i+6(-1)
1-6+5i
-5+5i
Taking -5 as common
-5(1-i)
I hope this will help you :)
Answer:
See answer below.
Step-by-step explanation:
2≥ g/-4
2( -4) ≥ g
-8 ≥ g
graph : Closed circle at -8 and shade to the left of -8
A=3
b=-6
c=1
x=(-b±<span>√(b^2-4ac))/2a
x=(6</span>±√(36-12))/(6)
x=(6±√(24))/(6)
x=(6±2√(6))/(6)
x=(3±√(6))/(3)
x≈1.82
x≈<span>.184</span>
