Algebra 2! "Value of x"?

So I am terrible at math in general and it would really mean a lot if someone could possibly help me!?

which of the following is a possible value of x in the following equation below? (4x-1 )(3x+5)=0

Comments

  • 4x-1=0

    3x+5=0

    x=1/4 or -5/3

  • W = --4, X = 2, Y = a million/2, and Z = --6 a million.) 10 - | XW | = 10 -- l (2)(--4) l = 10 -- l --8 l = 10 -- 8 = 2 2.) XZ - | XZ | = (2)(--6) -- l (2)(--6) l = -- 12 -- 12 = -- 24 3.) 3 | WX | + a million/4 | 4X + 8Y | = 3 l WX l + l X + 2Y l = 3 l (--4)(2) l + l (2) + 2(a million/2) l = 3 l --8 l + l 3 l = 24 + 3 = 27 4.) Z | Z | + X | X | = (--6) l --6 l + 2 l 2 l = --36 + 4 = -- 32

  • x = 1/4 , x = -5/3

  • If either term is 0 the result is 0. This means the solutions are 4x-1=0 and 3x+5=0. Solving these you get x=1/4 and x=-5/3=-1 2/3
