What is this quadratic equation written in standard form x2 - 10x - 6 equals 2x plus 1?

x2 - 10x - 6 = 2x + 1 Subtracting 2x + 1 from both sides gives: x2 - 12x - 7 = 0


Why is it no solution when 2x plus 7 equals 1?

Not sure what you mean; that equation certainly has a solution.


Solution of the equation 2x plus 3 equals 7?

2x + 3 = 72x = 4x = 2


What is the Factor x2 plus 2x 63?

x2+2x-63 = (x-7)(x+9) when factored


Can you solve x2 plus 2x - 63 equals 0?

x2+2x-63 = 0 When factorised: (x-7)(x+9) = 0 Therefore: x = 7 or x = -9


X2 plus 2x plus -6 equals 0?

x2 + 2x -6 = 0 x2 + 2x + 1 = 7 (x + 1)2 = 7 x = -1 ± √7


What is the solution set of the equation 2x-10 plus 7 equals 5?

(2x - 10) + 7 = 52x - 3 = 52x = 8x = 4


What is the value of x when x squared - 2x is 63 showing your work in the form of an equation?

x2-2x = 63 x2-2x -63 = 0 => x = -7 or x = 9 So x must = 9 Check: 92-18 = 63


What is the solution to x2 plus 2x equals 410 the solution is between 7 and 8?

The answer is (3.5)2 plus (4)2 equals 410.


What is the point of contact of the tangent line of y equals 2x plus k with the curve of y equals x squared -2x -7 showing all aspects of work?

If: y = 2x+k and y = x2-2x-7 Then: x2-2x-7 = 2x+k And so: x2-4x-7-k = 0 Using the discriminant of b2-4ac = 0 gives k a value of -11 Using the quadratic equation formula: x2-4x+4 = 0 gives x a duel value of 2 Therefore point of contact: (2, 0)


What is the solution of the equation of 4x equals 2x plus 14?

First, write it in a mathematical equation form:4x=2x+14Next, subtract 2x from both sides2x = 14Divide both sides by xx = 7


X2 plus 3x-7 equals 5x plus 8?

x2 + 3x - 7 = 5x + 8; thus, x2 + 3x - 7 - 5x - 8 = x2 - 2x - 15 = (x - 5)(x + 3) = 0. Therefore the solution is x = 5 or -3.
