Решите графически уравнения:

1) x²=x+6

2) x²+2x-3=0

3) x³=4x

4) x³=-x+3

1) x^2-x-6=0

a=1 b = (-1) c = (-6)

x12=1+-√1^2-4*1 * (-6)

2

x1=1+5

2

x2=1-5

2

x1=3

x2 = (-2)

2) x^2+2x-3=0

a=1 b=2 c = (-3)

x12 = (-2) + - √2^2-4*1 * (-3)

2

x1 = (-2) + 4

2

x2 = (-2) - 4

2

x1=1

x2 = (-3)

3) x^3-4x=0

x (x^2-4) = 0

x=0 или

x^2-4=0/+4

x^2=4

x=√4=2 = (-2)

x1=2 x2 = (-2)
