Q:
a) 1b) 5c) -1/2d) sqrt. 3not multiple choice, those are all the problems I need answeredthanks
Accepted Solution
A:
Answer:a) xΒ² β β3 x + Β½b) 5xΒ² β 5β3 x + β΅/βc) -Β½ xΒ² + Β½β3 x β ΒΌd) β3 xΒ² β 3 x + Β½β3Step-by-step explanation:Write the factored form of the quadratic:(x β (β3 + 1)/2) (x β (β3 β 1)/2)Distribute using FOIL (first, outer, inner, last):xΒ² β (β3 β 1)/2 x β (β3 + 1)/2 x + (β3 + 1)/2 (β3 β 1)/2Combine like terms:xΒ² β ((β3 β 1)/2 + (β3 + 1)/2) x + (β3 + 1)(β3 β 1)/4Simplify:xΒ² β ((β3 β 1 + β3 + 1)/2) x + (β3 + 1)(β3 β 1)/4xΒ² β β3 x + (β3 + 1)(β3 β 1)/4xΒ² β β3 x + (3 β β3 + β3 β 1)/4xΒ² β β3 x + Β½Now multiply by each new coefficient.b) 5xΒ² β 5β3 x + β΅/βc) -Β½ xΒ² + Β½β3 x β ΒΌd) β3 xΒ² β 3 x + Β½β3
