X2 - 2x - 13 equals 0?
x2 - 2x - 13 = 0 x2 - 2x + 1 = 14 (x - 1)2 = 14 x - 1 = ±√14 x = 1 ±√14 x ≈ {4.742, -2.742}
-2x plus 14 equals 0?
If -2x +14 = 0, -2x = -14, or x = 7.
-2 x - 14 equals 26?
-2x - 14 = 26 -2x = 26 + 14 x = -40/2 x = -20
what is 2x-1 x 2x-1?
(2x−1) ²
What is the quotient 3x3 - x2 - x - 1 x - 1?
3x3 - x2 - x - 1 = 3x3 - 3x2 + 2x2 - 2x + x - 1 = 3x2(x - 1) + 2x(x - 1) + 1(x - 1) = (3x2 + 2x + 1)(x - 1) So 3x3 - x2 - x - 1 /(x - 1) = (3x2 + 2x + 1)
X2 - 2x - 13 equals 0?
x2 - 2x - 13 = 0 x2 - 2x + 1 = 14 (x - 1)2 = 14 x - 1 = ±√14 x = 1 ±√14 x ≈ {4.742, -2.742}
How would you write one half of a number is fourteen more than two times the number?
(1/2)x =+14 + 2x or x/2 = 2x +14 or 1/2(x) = 2x + 14 --> x = 4x + 28 ----> 3x=-28 so x = -28/3
What is the slope of the line 14y-2x equals 28?
14y - 2x = 28 ie 7y - x = 14 ie 7y = x + 14 or y = (1/7)x + 14 The slope is the coefficient of x, or 1/7
7x-4x plus 2x plus 5 equals 2x plus 14?
7 x - 4 x + 2 x+5 = 2 x + 14 --- (1) Shift those terms containing "x" on left side and constants on other side 7 x - 4 x + 2 x - 2 x = 14 - 5 We will get 3 x = 9 Divide both sides by "3" we get; x = 3
How do you factor the expression xsquared minus 6x?
You're looking for factors of 196 that combine to make 28. If that's +196, the answer is (x - 14)(x - 14) or (x - 14)2 If that's -196, it gets ugly in a hurry.
What is -2x-6 equals 14?
-2x-6 = 14 -2x = 14+6 -2x = 20 x = -10
-2x plus 14 equals 0?
If -2x +14 = 0, -2x = -14, or x = 7.
Solve -2X - 4 10?
-2x -4 = 10 -2x = 14 -x = 14/2 -x = 7 x = -7 easy.
-2 x - 14 equals 26?
-2x - 14 = 26 -2x = 26 + 14 x = -40/2 x = -20
The sum of two consecutive integers is 15?
let x = 1st integer x + 1 = next consecutive integer x + x + 1 = 15 2x + 1 = 15 2x = 14 x = 7 x = 1 = 8
Factor 2x squared plus 2x plus xy plus y?
4
Solve -2x plus 14 equals 20?
-2x+14=20 -2x=20-14 -2x=6 -2x/-2=6/-2 x=-3
