X^2 + 4x + 8 = 0
( x + 2 ) ( x + 2 ) = 0
i am a mathematics teacher. if anything to ask please pm me
Answer:
1:3 ............... ......
x-2y = -2
x-2(-3x+8)=-2
mutiply the bracket by -2
(-2)(-3x)=6x
(-2)(8)=-16
x+6x-16=-2
7x-16=-2
move -16 to the other side
sign changes from -16 to +16
7x-16+16=-2+16
7x= -2+16
7x= 14
divide both sides by 7
7x/7=14/7
x=2
Find y by using the substitution method
y=-3x+8
y=-3(2)+8
-6+8
=2
Answer:(2,2)
1/2 - y (6y - 8)
1/2 -6y2 - 8y
the answer is A
