Question

256 – y²=0 3600 – b²=0 a² – 4900 = 0 12100 – b² = 0 решить уравнение

Answer 1

Y^2=256
y=16 или y=-16

b^2=3600
b=60 или b=-60

a^2=4900
a=70 или a=-70

b^2=12100
b=110 или b=-110

Answer 2

$256-y^2=0 \\ (16-y)(16+y)=0 \\ y=16 \\ y=-16$

$3600-b^2=0 \\ (60-b)(60+b)=0 \\ b=60 \\ b=-60$

$a^2-4900=0 \\ (a-70)(a+70)=0 \\ a=70 \\ a=-70$

$12100-b^2=0 \\ (110-b)(110+b)=0 \\ b=110 \\ b=-110$
