Step-by-step explanation:
To find the zeros let p(x) = 0 , that is
(x² - 1)(x² - 5x + 6) = 0
Factorise each factor
x² - 1 ← is a difference of squares and factors as (x - 1)(x + 1)
x² - 5x + 6 = (x - 2)(x - 3), thus
(x - 1)(x + 1)(x - 2)(x - 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
x + 1 = 0 ⇒ x = - 1
x - 2 = 0 ⇒ x = 2
x - 3 = 0 ⇒ x = 3
The zeros are x = ± 1, x = 2, x = 3
Answer:-7
Step-by-step explanation:
Number 5) A hill that rises 2 feet for every 10 feet of run. Because a longer run is not as steep as a short run.
Number 6) They all are parallel, they do not intersect.
Answer:
y= −1/2x+ 1/2
Step-by-step explanation:
Find the negative reciprocal of the slope of the original line and use the point-slope formula
y-y1=m(x-x1) to find the line perpendicular to y=2x−3.
Have two sets of parallel sides
