2(4x^2 - 7x + 5)
21
2x2 + 10 - 9x = 0 or 2x2 - 9x + 10 = 0 So (x - 2)*(2x - 5) = 0
you would first do 10+5x-5=0, then 5x+5=0 and is factored by 5(x+1)=0. or if you want to know what x equals with, x=-1
10-0 is actually 10 :)
Yes.
so 10 x0 equals 0 people its times and x is diffrent to plus.
a(-14-a) = 0 so a = 0 or a = -14
100x2-81
4(x + 1) = 0.
x2-2x-10-5 = 0 x2-2x-15 = 0 (x+3)(x-5) = 0 x = -3 or x = 5
D is the choice that is not true.
If you factor x2 - 3x - 10, you'll get (x-5) (x+2). If your equation is x2 - 3x -10 = 0, then x = 5, and x = -2.
