sif(x)=x^2-1,g(x)=x^2+x

s i f (x) = x^{2} - 1, g (x) = x^{2} + x

s = 0, s \in R, s = 0, s \in R, x = - 1, x = - 1, x = 1, x = 1, f \in R f = 0 f \in R f = 0

Solution steps

s i f (x) = x^{2} - 1

Rewrite

s i f (x)

in standard complex form:

0 + s f (x) i

0 + s f (x) i = x^{2} - 1

Rewrite

x^{2} - 1

in standard complex form:

(x^{2} - 1) + 0 i

0 + s f (x) i = (x^{2} - 1) + 0 i

Complex numbers can be equal only if their real and imaginary parts are equalRewrite as system of equations:

[0 = x^{2} - 1 s f (x) = 0]

[0 = x^{2} - 1 s f (x) = 0] : s = 0, s \in R, s = 0, s \in R, x = - 1, x = - 1, x = 1, x = 1, f \in R f = 0 f \in R f = 0

s = 0, s \in R, s = 0, s \in R, x = - 1, x = - 1, x = 1, x = 1, f \in R f = 0 f \in R f = 0

∣ Z + 5 i ∣ = i Z

(2 a + 1) + (2 b + 3) i = 5 + 12 i

0.022 i = \frac{1}{x \cdot i}

3 x + 4 y + (x + 2 y) i = 5 + 3 i

r (t) = (5 + t) i + t j
