(Points : 1)
{57, 71}

{-22, 36}

{-15, 29}

{-1, 15}



Question 4. 4. Solve the following equation by transforming it into a perfect square trinomial.

3x2 + 18x = 21
(Points : 1)
{-7, 1}

{-19, 13}

{-25, 7}

{-13,- 5}

Answer 1

14= 7×2 and 7²=49

Answer 2

do you want to upload all of your homework for the entire semester?

Answer 3

LOL !

Answer 4

Okay i don't need sass thanks

Answer 5

I would be willing to do it, how much are you paying ? 25cent per problem.
All steps and explanation guaranteed.

Answer 6

25 it is lol

Answer 7

hehe

Answer 8

\[3 x^2+18x=21 ~or ~3x^2+18 x-21=0\]
\[make ~the~coefficient~of~x^2~as~1~by~dividing~by~3\]
x^2+6x-7=0
now add both sides\[\left( \frac{ coefficient~of~x }{ 2 } \right)^2~i.e.,\left( \frac{ 6 }{ 2 } \right)^2=9\]
\[x^2+6 x+9=7+9\]
\[\left( x+3 \right)^2=4^2,x+3=\pm~4\]
solve for x.

Answer 9

Thank you but I got it figured out. :) thanks a lot.

Answer 10

correction
\[3 x^2+18x=21~or~x^2+6x=7\]
