Answer:


f(x) = 2(x + (5)/(4) {)}^(2) - (41)/(5)

Explanation:


f(x) = 2 {x}^(2) + 5x - 2


f(x) = 2( {x}^(2) + (5)/(2) x) - 2


f(x) = 2( {x}^(2) + (5)/(2) x + (25)/(16) ) - 2


f(x) + 2 * (25)/(16) = 2( {x}^(2) + (5)/(2) x + (25)/(16) ) - 2


f(x) = 2(x + (5)/(4) {)}^(2) - 2 - (25)/(8)


f(x) = 2(x + (5)/(4) {)}^(2) - (41)/(5)
