Let f(x) =X²-4 and g(x) = 3x+2
3f(x)+2g(x)=

Answer 1

`\boxed{\sf 3f(x) + 2g(x)= 3 {x}^(2) + 3 x - 8}`

Given:

f(x) = x² - 4

g(x) = 3x + 2

To Find:

`\sf 3f(x) + 2g(x)`

Explanation:

`\sf \implies 3f(x) + 2g(x) \\ \\ \sf \implies 3( {x}^(2) - 4) + 2(3x + 2) \\ \\ \sf \implies (3 * {x}^(2) ) - (3 * 4) + (2 * 3x) + (2 * 2) \\ \\ \sf \implies 3 {x}^(2) - 12 + 3x + 4 \\ \\ \sf \implies 3 {x}^(2) + 3x + ( - 12 + 4) \\ \\ \sf \implies 3 {x}^(2) + 3 x - 8`
