${x}^{2} + 2x - 8 = 0 \:$
is
a) 12
b) 2
c) 36
d) 48​

Answer 1

Answer:

hi mate

your answer is C) 36

by using formula b^2 -4ac

I hope it's helping you

Answer 2

$\huge {\mathcal{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}$

${\purple{\boxed{\large{\bold{D = {b}^{2} - 4ac }}}}}\\ \\ Here ,\\ a = 1, \: b = 2 \: and \: c = - 8 \\ so \\ D = {2}^{2} - 4 \times 1 \times ( - 8) \\ \\ D= 4 + 32 \\ \\ D= 36 \\ \\ Therefore, \: \\ {\red{\boxed{\mid{\bold{The \: discriminant \: value = 36}}}}}$

Option C is correct.
