Answer:

Answer is option d) x = -4 , x = -3

Step-by-step explanation:

[tex]given \: equation \: is \\ 2 {x}^{2} + 14x = - 24 \\ 2 {x}^{2} + 14x + 24 = 0 \: \\ dividing \: this \: equation \: by \: 2 \: we \: get \\ {x}^{2} + 7x + 12 = 0 \\ by \: factorization \\ (x + 4)(x + 3) = 0 \\ x = - 4 \: \: \: \:( or) \: \: \: x = - 3[/tex]
