solve(4*x^2=8) — step-by-step solution

Let's solve in

ℝ

4 x^{2} = 8

This expression can be factorized into:

4 \cdot (x^{2} - 2) = 0

Let's solve:

x^{2} - 2 = 0

Solutions found:

x = {- \sqrt{2}, \sqrt{2}}

The numeric value of:

x = {- \sqrt{2}, \sqrt{2}}

is:

x = {\approx -1.4142, \approx 1.4142}

▷Result: $x = {- \sqrt{2}, \sqrt{2}}$

▷▷Numeric:

x = {\approx -1.4142, \approx 1.4142}
