X2 plus 16x plus 55 equals?
Assuming you wish to make this equation equal zero, for x2 + 16x + 55 = 0, x = -5.
How do you factor x3 plus 5x2 minus 16x minus 80?
To factorise x3 + 5x2 - 16x - 80 I note that -80 = 5 x -16 and 5 & -16 are the coefficients of x2 and x. Thus I have: x3 + 5x2 - 16x - 80 = (x + 5)(x2 - 16) and the second term is a difference of 2 squares, meaning I have: x3 + 5x2 - 16x - 80 = (x + 5)(x + 4)(x - 4)
How do you factor x squared plus 16x minus 348?
x2 + 16x - 348 cannot be factored. Solving for x with the quadratic formula results in x = -8 - 2√103 and x = -8 + 2√103
How do you factor x2-16x plus 63?
(x - 7)(x - 9)
X2 - 16x plus 28 binomials trinomial?
That factors to (x - 14)(x - 2)
X2 plus 16x plus 55 equals?
Assuming you wish to make this equation equal zero, for x2 + 16x + 55 = 0, x = -5.
What is the LCM of x2 plus 16x plus 64 and x2 plus 3x-40?
x2 + 48x + 320
What number must you add to complete the square x2 plus 16x equals -7?
square root -5 minus 14 or - square root -5 minus 14
How do you factor x3 plus 5x2 minus 16x minus 80?
To factorise x3 + 5x2 - 16x - 80 I note that -80 = 5 x -16 and 5 & -16 are the coefficients of x2 and x. Thus I have: x3 + 5x2 - 16x - 80 = (x + 5)(x2 - 16) and the second term is a difference of 2 squares, meaning I have: x3 + 5x2 - 16x - 80 = (x + 5)(x + 4)(x - 4)
How do you factor x squared plus 16x minus 348?
x2 + 16x - 348 cannot be factored. Solving for x with the quadratic formula results in x = -8 - 2√103 and x = -8 + 2√103
How do you solve x2 plus 16x-80?
x2+16x-80 = 0 (x-4)(x+20) = 0 x = 4 or x = -20
What is the anwer xsquare-16x plus 48?
x2-16x+48 = (x-4)(x-12) when factored
How do you factor x2-16x plus 63?
(x - 7)(x - 9)
What is the LCM of x2 plus 4x and x2-4x?
x(x + 4)(x - 4) or x3 - 16x
X2 - 16x plus 28?
x2 - 16x + 28 = x2 -2x - 14x - 28 = x(x - 2) - 14(x - 2) = (x - 14)(x - 2)
Y equals x2 plus 16x plus 59?
Y=(x+8)^2-5
What number must you add to complete the square x2 plus 16x equals 3?
Half of the coefficient of x, squared. For example: x2 + 16x -3 you would add 8^2. Then you would have: x2 +16x +8^2 = 3-8^2 Which leads to: (x+8)^2 = -61
