Answer:
x=1.316 and x=-5.316
Step-by-step explanation:
Expand the the x+2= x^2 +4x+4
add 5 to 4 bc they in the same group, then subtract 16 from the other side so it equal to zero.
It should be x^2+4x+9-16=0 then do combine 9-16 which equals 7.
Put x^2+4x-7 into the quadratic formulas [tex]\frac{-4+/-\sqrt{4^{2*1*(-7)} } }{2*1}[/tex] (tried my best).
When the sq root is + its 1.316 when sq root is - is -5.316.
Hope this helps
