3x2+14x+8 = 0 x = -2/3 or x = -4
X2 plus 12x plus 36 equals 0?
x2+12x+36=0 2x+12x+36=0 14x+36=0 14x=-36 x=-36/14 x=-2 4/7
What are some hard math equations that equals 7?
How about finding the solutions of the quadratic equation: x^2-14x+49 = 0
What number must you add to complete the square of x2 plus 14x equals -5?
Improved answer:5x2+14x+5 = 5-5x2+14x+5 = 0Solve by completing the square:(x+7)2+5 = 0(x+7)2+5-49 = 0(x+7)2 = 44x+7 = + or - the square root of 44x = -7 + or - the square root of 44
What are the roots of the quadratic equation x2 - 14x plus 45 equals 0?
x2-14x+45=0(x-9)(x-5)=0x-9=0 & x-5=0x=9 & x=5
X2 - 14x equals -49 using factoring?
x2 - 14x = -49 ∴ x2 - 14x + 49 = 0 ∴ (x - 7)2 = 0 ∴ x = 7
How do you factor 8x2-14x 10 equals 0?
2(4x^2 - 7x + 5)
What is the fifth step in solving the eqution by completing the square 3x2 plus 14x plus 8 equals 0?
3x2+14x+8 = 0 x = -2/3 or x = -4
X2-14x equals -49 solve by factoring?
Re-arranging, x2 - 14x +49 = 0 Factorising, (x-2)(x-2) = 0, hence x=2.
49 plus 14x plus 2 equals?
-x2+14x=49
X2 plus 12x plus 36 equals 0?
x2+12x+36=0 2x+12x+36=0 14x+36=0 14x=-36 x=-36/14 x=-2 4/7
Solve the equation by factoring 15 equals 8x2-14x?
15 = 8x2 - 14x; whence, 8x2 - 14x - 15 = (2x - 5)(4x + 3) = 0. Therefore, x = 5/2 or -3/4.
What is Negative 7x plus 3 equals negative 15 divided by 2 help?
x = 1.5 because -7x + 3 = -15/2 -14x + 6 = -15 (x2) -14x + 21 = 0 (+15) 21 = 14x (+14x) 3 = 2x (/7) 1.5 = x
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
What does -8x-2 plus -4 equals?
-14x
