IM STUCK ! how do I determine the zeros if my x intercepts from the quadratic formula is this ! (in the picture) what do I do to find the y intercept ?!

The y-intercept is -3, but consider that 'a' is 4 and not 1, in your solving. Hope, I helped you.

Step-by-step explanation:

First, let's solve the quadratic equation given, and find the x-intercepts:

Using the quadratic equation:

But note that:

So,

Zeros/Roots:

The y-intercept is when x is equal to 0, so:

answer: 2/4

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
