What is x2 plus 14x plus 49?
(x2 + 14x + 49) = (x + 7)2
What number must you add to complete the square of x2 plus 14x equals -7?
49 x2 + 14x = -7 x2 + 14x + 49 = 42 (x + 7)2 = 42 x = -7 ± √42
X2 - 14x equals -49 using factoring?
x2 - 14x = -49 ∴ x2 - 14x + 49 = 0 ∴ (x - 7)2 = 0 ∴ x = 7
How do you Factoring perfect square of x2-14x plus 49?
x2 - 14x + 49 = (x - 7)2
What does -8x-2 plus -4 equals?
-14x
4x2 plus 28x plus 49?
4x2 + 28x + 49 = 4x2 + 14x + 14x + 49 = 2x(2x + 7) + 7(2x + 7) = (2x + 7)(2x + 7) or (2x + 7)2
X times fourteen times x plus 1 equals?
(14x)(x)+1 14x^2 + 1
X2-14x equals -49 solve by factoring?
Re-arranging, x2 - 14x +49 = 0 Factorising, (x-2)(x-2) = 0, hence x=2.
What is the square root of x to the power of 2 minus 14x plus 49?
(x - 7) is.
What is the solution of x squared-14x plus 49 equals 4?
Notice that the left side of the equation is a perfect square (x - 7)2 = x2 -14x + 49. so (x - 7)2 = 4. Take square root of both sides: x - 7 = ± 2, x = 9, or x = 5.
What is parallel to 14x plus 21y plus 42 equals 0?
y=-2/3x with any y-intercept except -2.
What is 12x2 plus 14x plus 4 equals 0?
It is a quadratic equation and the values of x are -1/2 or -2/3Do you mean 12x2+14x+4 = 0If so then x = -2/3 and x = -1/2
