To find the zeros set the equation equal to zero:

x^2 - 5x +4 = 0

Factor:

(x-4) (x-1) = 0

Now solve each set of parenthesis so that they equal zero:

(x-4) = 0, x =4

(x-1) = 0, x = 1

The zeros are 1,4

The length of a rectangle is 6 cm less than twice its width. Find the dimensions of the rectangle if its areais 108cm

valentinak56 [21]

L=2w-6

area = L x W

108=(2w-6)w

108 = 2w^2-6w

2w^2-6w-108 = 0

2(w^2-3w-54)=0

2(w-9)(w+6) = 0

w=9

L= 2(9)-6 = 12

12*9 = 108
