Find coordinates of y = 4x^2+ 40x+112

Step-by-step explanation:

y = 4x²+ 40x+112 (:4)

x²+ 10x+ 28.

28

1. |. 28

2. |. 14

4. |. 7

(x+4)(x+7)=0

x= -4. V. x= -7

Now fill in the x= -4 in y so you get the Y-coordinate and do the same for x= -7

Anseer should be like: 'The coordinates are (x, y) and (x, y)

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.
