Answer:

[tex]x = 6 \: \: or \: \: x = 7[/tex]

Step-by-step explanation:

[tex] {x}^{2} - 13x + 28 = - 14 \\ \\ {x}^{2} - 13x + 28 + 14 = 0 \\ \\ {x}^{2} - 6x - 7x + 42 = 0 \\ \\ x \times (x - 6) - 7(x - 6) = 0 \\ \\ (x - 6) \times (x - 7) = 0 \\ \\ x - 6 = 0 \\ x - 7 = 0 \\ \\ x = 6 \: \: or \: \: x = 7[/tex]

hope its help
