Question

find the value of 6y^2 -24y -75 if y = -2​

Answer 1

Answer:

-3

Step-by-step explanation:

y= - 2 so $y^{2}$ will be 4

6*4 = 24

24(-2)= -48

So the equation becomes

24-(-48)-75 = 24+48-75 = 72-75 = -3

Answer 2

Answer:

-3

Step-by-step explanation:

= 6y^2-24y-75

= 6x(-2) -24x (-2) -75

= 6x4 + 48 - 75

= 24 + 48 - 75

= 72 - 75

= -3
