X^2+2x= -8
x^2+2x+1= -8+1
(x+1)^2= -8+1
(x+1)^2=-7
x+1= √-7
The answer is No Solution because the root of a negative number is not a real number.
Answer:
subtract 2.4 from both sides, simplify to -3x=16.8, divide by -3, simplify to x=-5.6.
Step-by-step explanation:
-3x + 2.4 = 19.2
v <u>-2.4</u> <u>-2.4</u>
v 0 16.8
<u>-3x</u>=<u>16.8</u>
-3 -3
x=-5.6
