Answer:
x = -2+√3i and -2-√3i
Step-by-step explanation:
The formula for the general formula is expressed as;
x = -b±√b²-4ac/2a
Given the expression
x²+4x+7 = 0
a = 1, b = 4 and c = 7
Substitute
x = -4±√4²-4(1)(7)/2(1)
x = -4±√16-28/2
x = -4±√-12/2
x = -4±√4*-3/2
x = -4±2√-3/2
x = -4±2√3i/2
x = -4+2√3i/2 and -4-2√3/2
x = -2+√3i and -2-√3i
If I’m not wrong I think it’s x+1
Answer:
<u>-2</u>
Step-by-step explanation:
<u>Given</u> :
- An example of a coefficient ⇒ '11' in 11kk
<u>Solving</u> :
- The coefficient is the part that precedes the variable(s)
- Therefore, on solving -k - k
- ⇒ -2k
- ⇒ <u>-2 is the coefficient</u>
Answer:
I got x<equal to -11 or x>equal to4
Step-by-step explanation:
x^2+15x+44=0
(x+4)(x+11)=0(Factor left side of equation)
x+4=0 or x+11=0(Set factors equal to 0)
x=−4 or x=−11
Check intervals in between critical points. (Test values in the intervals to see if they work.)
x<−11(Works in original inequality)
−11<x<−4(Doesn't work in original inequality)
x>−4(Works in original inequality)
Answer:
x<−11 or x>−4
Hey there!
4(12 + 6)
4(12) + 4(6)
4(12) = 48
4(6) = 24
48 + 24 = ?
48 + 24 = 72
Answer: 72 ☑️
Good luck on your assignment and enjoy your day!
