Question

y^3+2y^2+12y+16=28

I really need a step by step explanation because I want to understand. Thank youuuuu! Branliest for explanation :)

Answer 1

Answer:

$y = 0.835193$ (use the '≈' )

Step-by-step explanation:

$y^3+2y^2+12y+16=28$ (original equation)

$y^3+2y^2+12y+16 - 28 =28 -28$ (subtract 28 from both sides)

$y^3+2y^2+12y-12=0$ (new equation)

then use the cubic formula (i don't really know how to explain the process through a screen. I'm sorry! Hopefully, this helps enough though)
