If 4y plus 9 equals 17 what does y equal?
y = 2 (4X2=8) +9 = 17
What is the length of one side of this square 4x2 - 4xy plus y2?
4x2 - 4xy + y2 = (2x - y)2 so the length of the side of the square must be 2x-y.
How do you factor 4x2 -y2-6y-9?
It is (2x +y + 3)*(2x - y - 3).
Find vertex and roots of y equals 4x squared plus 6?
y = 4x2 + 6 ory = 4x2 + 0x + 6, where a = 4, b = 0 and c = 6x-coordinate of the vertex = -b/2a = -0/2(4) = 0y-coordinate of the vertex = 4(02) + 6 = 6vertex is (0, 6)(Or you can say: Since the vertex of y = x is (0, 0), and this graph is shifted 6 units upward in the y-axis, then the vertex of y = x + 6 would be (0, 0 + 6) or (0, 6)Substitute 0 for y in order to find the roots.y = 4x2 + 60 = 4x2 + 60 - 6 = 4x2 + 6 - 6-6 = 4x2-6/4 = 4x2/4- 6/4 = x2± √(-6/4) = x± [√(6/4)]i = x x = [(1/2)√6]i or x = - [(1/2)√6]i
What is the vertex form of y -4x2-6x?
The question does not contain an equation: only an expression. An expression cannot have a vertex form.
