Answer 2

Answer:-√14/4,2

Step-by-step explanation:

First solv the equation

(X-1)2+(X+2)2+3(x+1)=0

Use formula (a-b)2 and (a+b)2

X2+1-2x+x2+4+4x+3x+3=0

2x2+5x+8=0

Now use formula

x = −b +- √(b2 − 4ac)/2a

First use +

= -5+√(25-4×2×8)/2×2

Now square both side

X2=(25+25-64)/16

=-14 /16

Both side remove square

X=√14/4 first value of X

Now use -

Than

X= -5-√(25-64)/4

Both side square

X2=(25-(-39)/16

X2=25+39)/16

X2=64/16

X2=4

X=2 second value of X
