Question

Perform the operation.
(4x^2 + 6x + 7) - (-8x^2 – 2x + 6)

Answer 1

`12 {x}^(2) + 8x + 1`

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

`(4 {x}^(2) + 6x + 7) - ( - 8 {x}^(2) - 2x + 6) \\ = 4 {x}^(2) + 6x + 7 + 8 {x}^(2) + 2x - 6 \\ = 4 {x}^(2) + 8 {x}^(2) + 6x + 2x + 7 - 6 \\ = 12 {x}^(2) + 8x + 1`

`\circ \: \: { \underline{ \boxed{ \sf{ \color{green}{Happy\:learning.}}}}}∘`
