X^2 + 4x + 8 = 0
( x + 2 ) ( x + 2 ) = 0
i am a mathematics teacher. if anything to ask please pm me
The ^3 and ^2 are exponents sorry I don’t think you can type exponents on a keyboard, 6x^3+22x^2+3x-6
Answer: (8,8)
Step-by-step explanation:
First you need to get a x or y by itself.
I choosed to get y by itself since it would be faster.
-2x + y = -8 (first get -2x to the other side so add 2x)
y = -8 + 2x (then you want to insert that to the other equation)
-x + 4( -8 +2x) = 24 -> -x -32 + 8x = 24 -> 7x -32 = 24
(add 32 to the other side)
7x = 56 (divide 7 to 56 to get x) x = 8
now insert into the other equation
-2( 8 ) + y = -8 -> -16 + y = -8 ( move -16 to the other side, so add 16)
then you get your answer, y= 8
