-x2 plus 6x plus 16?
-x2 + 6x + 16 = -(x2 - 6x - 16) = -(x - 8)(x + 2) = -(8 - x)(x + 2)
How do you solve x2 plus 6x equals -9?
2x+6x=-9 => 8x=-9=> x=-8/9
What is -x2 plus 6x plus 8?
4x+8
X2 plus 6x plus 1 equals 0?
x2 + 6x + 1 = 0 x2 + 6x + 9 = 8 (x + 3)2 = 8 x + 3 = ± 2√2 x + 3 = -3 ± 2√2 x ∈ {-3 - 2√2, -3 + 2√2}
What are the roots of the quadratic equation x2 - 6x plus 8 equals 0?
x = 2 and x = 4
X squared plus 6x plus 8 equals 0?
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
Factor x2 plus 6x plus 8?
x2 + 6x + 8 = (x + 4)(x + 2)
-x2 plus 6x plus 16?
-x2 + 6x + 16 = -(x2 - 6x - 16) = -(x - 8)(x + 2) = -(8 - x)(x + 2)
How do you solve x2 plus 6x equals -9?
2x+6x=-9 => 8x=-9=> x=-8/9
What are the solutions for the quadratic equation x2 plus 6x equals 16?
x2 + 6x = 16=> x2 + 6x - 16 = 0=> x2 + 8x -2x - 16 = 0=> (x+8)(x-2) = 0=> x = -8 or x = 2So, the solutions of the quadratic equation x2 + 6x = 16 are -8 and 2.
What is -x2 plus 6x plus 8?
4x+8
X2 plus 6x plus 1 equals 0?
x2 + 6x + 1 = 0 x2 + 6x + 9 = 8 (x + 3)2 = 8 x + 3 = ± 2√2 x + 3 = -3 ± 2√2 x ∈ {-3 - 2√2, -3 + 2√2}
What are the roots of the quadratic equation x2 - 6x plus 8 equals 0?
x = 2 and x = 4
What is the minimum of x2 plus 6x plus 8?
(-3,-1)
Factor the expression x squared plus 6x plus 8?
x2 + 6x + 8 =(x + 2)(x +4)
X2 equals -6x equals?
8
X2 - 6x equals -8?
This is a quadratic equation question in finding the possible values of x x2 - 6x = - 8 x2 - 6x + 8 = 0 Factorise the expression in the equation: (x-2)(x-4) = 0 Therefore: x = 2 or x = 4
