3. Determine the x-intercepts of each parabola. You may be able to factor or you might
need to use the quadratic formula.

a)
y = 2x2 - 24x + 70

b)
y = 4.2x2 - 3.5x - 1.9

i don't even know man. edge inuity be messing with us. i had to ask a question too.

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
