Answer:
x = ± 
Step-by-step explanation:
3x² + 7 = 28 ( subtract 7 from both sides )
3x² = 21 ( divide both sides by 3 )
x² = 7 ( take square root of both sides )
x = ± 
that is x = -
, x = 
Answer:
y = -948

Answer:
3x2-3x+9
Step-by-step explanation:
(h-k)(3)
(X2+1-(x-2))(3)
(x2+1-x+2)(3)
3x2+3-3x+6
3x2-3x+9
2/32. Divide 32 by 4 to equal 8, and then divide 8 by 3 because that’s how much you painted, a third of a fourth
