What is the solution set of the quadratic equation 8x2 plus 2x plus 1 0?
There is no equals sign visible but, taking the equation to be8x2 + 2x + 1 = 0,the solutions are the complex conjugate pair, -1.25 ± 0.330719*i where i is the imaginary square root of -1.
-2X 2 plus 17x-35 equals 0?
-2x^2 + 17x - 35 = 0 = (-2x + 7)(x - 5) x =7/2 or 5
What is the y-intercept of y equals 2X plus 5?
y = 2x + 5At the y-intercept, x=0.y = 0 + 5y = 5
2x - 5y plus 15 equals 0 written in slope-intercept form?
2x-5y+15=0 -5y=-2x-15 y=(2/5)x+3
What is 2x plus -2x?
It is 2x+(-2x) = 0
What is 8x2-2x-15 equals 0?
8x2-2x-15 = 0 (2x-3)(4x+5) = 0 x = 3/2 or x = -5/4
What is the answer 8x2-2x-3 equals 0?
8x2-2x-3=0 (2x+1)(4x-3)=0 2x+1=0 or 4x-3=0 x=-1/2 or x=3/4
How do you solve 8x2 plus 16x plus 8 equals 0?
8x2 + 16x + 8 = 0
What is the solution set of the quadratic equation 8x2 plus 2x plus 1 0?
There is no equals sign visible but, taking the equation to be8x2 + 2x + 1 = 0,the solutions are the complex conjugate pair, -1.25 ± 0.330719*i where i is the imaginary square root of -1.
What is x equals to 2x-2x plus 456 equals 0?
x=0
-2x plus 1 equals 2x plus 1?
x = 0
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 the discriminant of 8x2-2x plus 8 equals 0?
(-2)2-4*8*8 = -252 The discriminant is less than zero so there's no solution to the quadratic equation.
What is 2x plus 8y plus 7 equals 0?
2x = -7 - 8y
-2x plus 14 equals 0?
If -2x +14 = 0, -2x = -14, or x = 7.
-2x plus 16 equals 0?
-2x+16 = 0 -2x = -16 x = 8
What are the 2 solutions to the equation x plus 3 divided by 3x plus 1 equals 2x-1 divided by 3-2x?
Cross-multiplying gives: (x + 3)(3 - 2x) = (3x + 1)(2x - 1) ie -2x2 - 3x + 9 = 6x2 - x - 1 add 2x2 to each side: -3x + 9 = 8x2 - x - 1 add 3x to each side: 9 = 8x2 + 2x - 1 subtract 9 from each side: 8x2 + 2x - 10 = 0 divide by 2: 4x2 + x - 5 = 0 Factors are: (4x + 5)(x - 1) x = -1.25 or 1
