(x + 2)(x2 + 3x – 40) = 0 18. x3 + 3x2 – 54x = 0Answer by OnlyJust(1)   (Show Source): You can put this solution on YOUR website!Solve each equation. 15. (x – 1)(x2 + 5x + 6) = 0 Simplify! Take away the brackets: Add the values in the first brackets to the values in the second Brackets: 5x + x = 6x 6 + -1 = 5. So now you have x2 + 6x + 5 = 0 Minus the five from the equation and that gives you x2 + 6x = -5 u work out the rest dumbass 16. x3 - 10x2 + 16x = 0 17. (x + 2)(x2 + 3x – 40) = 0 18. x3 + 3x2 – 54x = 0
