The x value of the vertex in
ax^2+bx+c is -b/2a
y value is just sub for x
3x^2-6x+5
x value of vertex is -(-6)/(2*3)=6/6=1
sub back
y=3(1)^2-6(1)+5
y=3(1)-6+5
y=3-1
y=2
vertex is (1,2)

Answer:
323563
Step-by-step explanation:
Answer:
9(x² + 5y⁴) (x² - 5y⁴)
Step-by-step explanation:
9x⁴ - 225y⁸
factor out a 9
9(x⁴ - 25y⁸)
factor (x⁴ - 25y⁸)
(x⁴ - 25y⁸)
x² • x² = x⁴
5y⁴ • -5y⁴ = -25y⁸
(x² + 5y⁴) (x² - 5y⁴)
↓
9(x² + 5y⁴) (x² - 5y⁴)
