x2 + 2x - 15 = (x - 3)(x + 5)
X2 plus 2x plus -6 equals 0?
x2 + 2x -6 = 0 x2 + 2x + 1 = 7 (x + 1)2 = 7 x = -1 ± √7
2x equals x2 plus 4x-3?
2x = x2 + 4x - 3 x2 + 2x - 3 = 0 (x - 1)(x - 2) = 0
2x squared plus 2x minus 8 equals?
2x2 + 2x - 8 = 2(x2 + x - 4). This can take any value greater than or equal to -8.5
Vertex for y equals x2 plus 2x plus 1?
The vertex is at (-1,0).

What is the value of X2 plus X?
The answer would be 3x if 'X2' is '2x', but if 'X2' is x2, then the total answer would be x2 + x.
Solve the equation y' plus x2y equals x2?
(2x)ysquared
What is x2 plus x2 mean?
If you have an equation of x2 plus x2, it is the same as saying 2 times x plus 2 times x. This can be written as 2x + 2x or x2 + x2. It is the same, then, as 4x. For example, if x equals 5: 2(5) + 2(5) = 10 + 10 = 20. 20 also equals 4(5).
What is the solution to x2 plus 10x plus 1 equals -12 plus 2x?
x2+10x+1 = -12+2x x2+10x-2x+1+12 = 0 x2+8x+13 = 0 Solving by using the quadratic equation formula: x = - 4 - or + the square root of 3
Y equals x2 plus 2x plus 1?
y = x2 + 2x + 1zeros are:0 = x2 + 2x + 10 = (x + 1)(x + 1)0 = (x + 1)2x = -1So that the graph of the function y = x + 2x + 1 touches the x-axis at x = -1.
What are solutions for x2 plus 10x plus 1 equals -12 plus 2x?
x2+10x+1 = -12+2x x2+8x+13 = 0 The solution: x = -4 + the square root of 3 or x = -4 - the square root of 3
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)
