$- 6 {x}^{2} - x - 3$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}$

$( - 2 {x}^{2} - 5x + 3) + ( - 4 {x}^{2} + 4x - 6) \\ \\ = - 2 {x}^{2} - 5x + 3 - 4 {x}^{2} + 4x - 6 \\ \\Combining \: the \: like \: terms, \: we \: have \: \\ \\ = - 2 {x}^{2} - 4 {x}^{2} - 5x + 4x + 3 - 6 \\ \\ = - 6 {x}^{2} - x - 3$

Mathematics

m = 1/3

Step-by-step explanation: Lets solve the equation |6m - 2| = 0.

|6m - 2| = 0

Find absolute values of 6m - 2

-6m + 2 = 0 (Now solve both sides of the equation.)

-6m + 2 - 2 = 0 - 2

-6m = -2

-6m/-6 = -2/-6

m = 1/3
