Question

Find the sum of zeros of 2x^2+kx_6

Answer 1

Answer:-k/2

Step-by-step explanation:

assuming your equation equation to be 2x^2 +kx - 6

the sum of roots of equation is -b/a.

therefore  sum of roots is -k/2.

Answer 2

Answer:

$\large{ \underline{ \underline{ \blue{answer}}}}\large\blue{ = 4 \sqrt{3} }$

Step-by-step explanation:

$\mathfrak{\large{ \blue{\underline{\underline{to \: find}}}}} \large \blue{ = 2 {x}^{2} + kx - 6 = 0 } \\ \large\blue{formula \: of \: discrimanant } \\ \large\blue{d = {b}^{2} - 4ac = 0 } \\ \large\blue{ {k}^{2} - 4(2)( - 6) = 0 } \\ \large\blue{ {k }^{2} + 48 = 0 } \\ \large\blue{k = \sqrt{48} }\large\blue{k = 4 \sqrt{3} }\large\blue{ = answer}$
