(х+3)²-16= (1-2х)²
x^2 +6x+9-16=1+4x^2-4x
x^2-4x^2+6x+4x+9-16-1=0
-3x^2+10x-8=0
D=b^2-4ac=100-4*(-3)*(-8)=100-12*8=4
x1 = -b+[tex]\sqrt{D}[/tex] /2a = -10+2/2*(-3) = -8/-6=8/6=4/3=1 1/3
x2 = -b-[tex]\sqrt{D}[/tex] /2a = -10-2/2*(-3)=-12/-6=12/6=2
[tex]\sqrt{x}[/tex]Ответ:
x^2+6x+9-16=1-4x+4x^2
D=b^2 - 4ac= 100-96=4
[tex]\sqrt{D}[/tex]=2
x1=-b+[tex]\sqrt{D}[/tex]/2a=-10+2/-6=8/6=4/3=1,1/3
x2=b-[tex]\sqrt{D}[/tex]/2a=-10-2/-6=-12/-6=2
