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
