Find the x-intercepts of
x^2 - 4x +1=0
using any method. Show as much work as possible for full credit.

There are 2 real solutions

Step-by-step explanation:

Calculate the discriminant

Simplify the expression

Then you get 2 solutions.

To find the x-intercept, substitute in  0  for  y

and solve for x(−2+√5,0),(−2−√5,0) hope I helped :)

14

step-by-step explanation:

14 x 3 = 42

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
