Odpowiedź:
Te liczby to -11 i 5 oraz 11 i 5
Szczegółowe wyjaśnienie:
x
x+6
[tex]x^{2} +(x+6)^{2} =146\\x^{2} +x^{2} +12x+36=146\\2x^{2} +12x-110=0\\[/tex]
[tex]x^{2} +6x-55=0\\[/tex]
delta = [tex]b^{2} -4ac = 36-4*1*(-55)=36+220=256\\[/tex]
pierwiastek z delty = 16
[tex]x_{1} = \frac{-b-pierw. delta}{2a} = \frac{-6-16}{2} =\frac{-22}{2} =-11[/tex]
[tex]x_{2} = \frac{-b+pierw. delta}{2a} =\frac{-6+16}{2} =\frac{10}{2} = 5[/tex]
