Solve 2x2 + 26 = 0 to identify the roots.
zalisa [80]

Answer:

x=+/-i\sqrt{13}

Step-by-step explanation:

To find the roots, factor and set equal to 0 or use the quadratic formula. This quadratic equation does not factor and must be solved using the quadratic formula.

x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}

where a = 2, b=0, and c=26

x=\frac{0+/-\sqrt{0^2-4(2)(26)} }{2(2)} \\x=\frac{+/-\sqrt{-208)} }{4} \\x=\frac{+/-i\sqrt{16*13)} }{4}\\x=\frac{+/4i\sqrt{13} }{4}\\x=+/-i\sqrt{13}
