To answer equation there is only one solution which is, x=12
Axis of symmetry = -b/2a
y + 3x - 6 = -3(x-2)² + 4
y + 3x - 6 = -3 ( x²-4x+4) + 4
y + 3x - 6 = -3x² + 12x -12 + 4
y + 3x - 6 = -3x² + 12x -8
y = -3x² + 12x - 3x -8 + 6
y = -3x² + 9x -2
(a=-3, b=9, c=-2)
Axis of symmetry = -b/2a = -9/2(-3) = -9 / -6 = -3 / -2 = 3/2
Hence, option A) x=3/2 is the correct answer.
Yes because simplified 9/15 equals 3/5 and 6/10 also equals 3/5

Step-by-step explanation:
Answer:
-2x² + 10x - 12
Step-by-step explanation:
Given the expression 2(5x+3)−2(x^2 −3)
Expand
2(5x+3)−2(x^2 −3)
= 2(5x)+2(3) -2(x²)-2(-3)
= 10x + 6 - 2x²+6
= 10x -2x²+12
Express in standard form
= -2x² + 10x - 12
