Use the quadratic formula to write a quadratic equation that has the solutions x=-4 ± 2/6.
2 answers:
Answer:
general formula
x²-(a+b)x+(ab)
where a is alpha
and b is beta
x=-4+2/6 or x=-4-2/6
x=-1/3 or x=-1
a+b=-1/3 + -1 =-4/3
ab= -1/3 x -1 =1/3
quadratic equation
x²-(-4/3)x + 1/3=0
x² + 4/3x + 1/3=0
multiply through by 3
3x² +4x +1=0

Answer:The correct answer is 16
Step-by-step explanation:
4^2= 16
16-6/2+3
16-3+3
13+3=16
1.y=-2x-3
2.y=2x+1
3.y=-3x-3
4.y=1/2x+2
2x -2x - 3 = 2x - 2x - 5 <em>subtract 2x from both sides</em>
-3 = -5 FALSE
