Question

Which equation has the solutions x=1+or- /5?

A. x2 + 2x + 4 = 0
B. x2 – 2x + 4 = 0
C. x2 + 2x – 4 = 0
D. x2 – 2x – 4 = 0

Answer 1

The answer would be C

Answer 2

Answer:

There is no quadratic equation which has solution x = 1 or -5

Step-by-step explanation:

For part A)

$x^{2}+2x+4$

$\mathrm{Could\:not\:factor\:further}$

$\mathrm{Factor}\:0$

For part B)

$x^{2}-2x+4$

$\mathrm{Could\:not\:factor\:further}$

$\mathrm{Factor}\:0$

For part C)

$x^{2}+2x-4$

$\mathrm{Could\:not\:factor\:further}$

$\mathrm{Factor}\:0$

For part D)

$x^{2}+2x-4$

$\mathrm{Could\:not\:factor\:further}$

$\mathrm{Factor}\:0$

There is no quadratic equation which has solution x = 1 or -5
