Y = X2 + 18X + 52
set to 0
X2 + 18X + 52 = 0
subtract 52 from each side
X2 + 18X = - 52
now, halve the coefficient of the variable term (18), square it and add it to both sides
X2 + 18X + 81 = - 52 + 81
now, factor on left and gather terms on right
(X + 9)2 = 29
(X + 9)2 - 29 = 0

What is the vertex of x2 plus 18x plus 19?
The vertex is (-9, -62).
What is the slope of line given by the equation below Y equals -18x plus 17?
y=-18x+17. Since this is already in Slope-Intercept form, we can determine that the slope is negative 18.
What is the vertex form of y -3x2 - 18x - 20?
The question contains an expression, not an equation and so there is no solution.
9x2-18x plus 9 equals 0 what is the discriminant?
The discriminant is 0.
What is 2x4 plus 8x3 plus 18x?
(2x4) + (8x3) + 18x 8 + 24 + 18x 32 + 18x

How do you solve 11x equals 20x Plus 18?
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
2X2 plus 18X equals 20?
2x2+18x = 20 2x2+18x-20 = 0 x2+9x-10 = 0 (x+10)(x-1) = 0 x = -10 or x = 1
How many real number solutions does the equation have y equals 3x2 plus 18x plus 27?
It has one double solution.
What is 10x plus 17 equals 4x-1?
10x + 17 = 4x - 16x = -18x = -3
What is the x intercept of 18x plus 12y equals 72?
18x + 12y = 72 to get x-int. put y=0 18x + (12)(0) = 72 18x = 72 x = 4 your x-intercept is 4. this is the place where the line goes through the x-axis.
What is x equal to in the math problem 18x equals 198?
18x= 19818x/18 = 198/18x = 11
-5 plus 12x equals 18x plus 7?
-5 + 12x = 18x + 7Subtract 7 from each side:-12 + 12x = 18xSubtract 12x from each side:-12 = 6xDivide each side by 6:-2 = x
