Discriminant review
Discriminant reviewThe discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
Given those zeros you have
X=0, x=1, and x=7
Since your factors are set equal to zero you just rewrite what’s above to equal 0.
X is just x
X=1 is (x-1)
X=7 is (x-7)
So your function is
x(x-1)(x-7)
Answer:
x = - 4 or x = 20
Step-by-step explanation:
Given R is the midpoint of AM, then
RA = MR , substitute values
x² - 16x = 80 ( subtract 80 from both sides )
x² - 16x - 80 = 0 ← in standard form
(x - 20)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 20 = 0 ⇒ x = 20
x + 4 = 0 ⇒ x = - 4
Answer:
Area
Step-by-step explanation:
Perimeter is just the border of something, and when you paint a wall you want it to cover the whole surface, so you use area. Area includes the whole surface of a given shape.
