2) Amy added two trinomials and got a sum of 10.x2 + 7x - 5. a) If the one of the trinomials was 3x2 - 2x - 10, find the second trinomial added.

b) Make a different pair of trinomials that have the same sum as Amy's.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
