What is x2 plus 7x equals - 2x2 plus 6 in the form ax2 bx c equals 0?
x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0
If y equals -2 when x equals 4 find x when y equals 5?
x1:y1 = x2:y2 4:-2 = x2:5 x2 = (4*5)/-2 x2 = -10
How do you solve x to the 4 - x to the 2 plus c equals zero?

Cx2 plus 12-4 equals 20 what is c?
2c+(12-4)=20 Simplify the expression in the parentheses first. 2c+8=20 Subtract 8 from both sides of the equation. 2c=12 Divide both sides of the equation by 2. c=6
What number is needed to complete the square x2 23x equals 0?
x2 23x equals 0
What is x2 plus 7x equals - 2x2 plus 6 in the form ax2 bx c equals 0?
x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0
What does x2 plus x2 equals?
x2 + x2 = 2x2
If y varies inversely as the square of x and y equals 4 when x equals 5 findy y when x is 2?
y varies inversely as x2 so y = c/x2 for some constant c. When x = 5, y = 4 So c = x2y = 100 that is y = 100/x2 Then, when x = 2, y = 100/4 = 25
If y equals -2 when x equals 4 find x when y equals 5?
x1:y1 = x2:y2 4:-2 = x2:5 x2 = (4*5)/-2 x2 = -10
Is the Nike aero fuse cx2 or exo grid better?
Nike Aero Fuse Cx2

What number is needed to complete the square x2 23x equals 0?
x2 23x equals 0
How do you solve x2 plus 4x equals 1?
x2 + 4x = 1 x2 + 4x - 1 = 0 in the quadratic formula (b2+- Sqr(4ac))/2a, a = 1 b = 4 c = -1 so x = 8 +- i
If a plus b plus c equals x plus y plus z then prove a2 plus b2 plus c2 equals x2 plus y2 plus z2?
a2+b2+c2=x2+y2+z2 divide each side by 2 (a2+b2+c2)/2=(x2+y2+z2)/2 a+b+c=x+y+z
Determine the value of c that makes the trinomial a perfect square x to the power of 2 plus 8x plus c show your work?
Think of it in reverse - trying to get it in the form of (x + a)2 This equals x2 + 2ax + a2 Compare the coefficients&constants to those of the original equation: x2 + 8x + c = x2 + 2ax + a2 2a = 8 and c = a2 a = 4, so c = 16
What does x2 plus 6-40 equal?
It equals x2 - 34
