Factor completely -use 2 methods- 4x squared plus 4x minus 8?
4x2+4x-8 4(x2+x-2) and (4x+8)(x-1)
What is the answer to 4x-3 equals 5?
4x - 3 = 5 4x = 5 + 3 4x = 8 x = 8/4 x = 2
What is 4x-7 equals 1?
4x - 7 = 1 Therefore, 4x = 8 x = 8/4 x = 2
4(x+2)?
8
What is an example of justify in math?
To justify something in math is to prove it. Example: Justify 4x = 8 when x = 2. When x = 2, 4(2) = 8. Done. By doing this I justified that 4x = 8 when x = 2.
What is the factor of 16xsquared-8x 1?
(4x - 1)(4x -1) or (4x - 1)2
What is 4x divide by 8?
0.5
Find the value of x: 2(4x + 4) = (4x - 12)?
2(4x + 4) = (4x - 12) 8x + 8 = 4x - 12 8x - 4x + 8 = 4x - 4x - 12 4x + 8 = -12 4x + 8 - 8 = -12 - 8 4x = -20 4x/4 = -20/4 x = -5
Which number when substituted for x makes the equation 4x 8?
If 4x = 8, then x = 2
Factor completely -use 2 methods- 4x squared plus 4x minus 8?
4x2+4x-8 4(x2+x-2) and (4x+8)(x-1)
2-x greter than 3x plus 10?
2 - x > 3x + 102 - x + x > 3x + x + 102 > 4x + 102 - 10 > 4x + 10 - 10-8 > 4x-8/4 > 4x/4-2 > x or x < -2
What is the answer to 4x-3 equals 5?
4x - 3 = 5 4x = 5 + 3 4x = 8 x = 8/4 x = 2
What is 4x-7 equals 1?
4x - 7 = 1 Therefore, 4x = 8 x = 8/4 x = 2
What is the factor of X3 - 2x2 - 4x plus 8?
x3 - 2x2 - 4x + 8 = (x2 - 4)(x - 2) = (x + 2)(x - 2)(x - 2)
4x - 7 equals -15 what is x?
4x - 7 = -15 4x = -8 x = -2
What is the solution set for x2-4x equals 8?
x2 - 4x = 8 x2 - 4x + 4 = 8 + 4 (x - 2)2 = 12 x - 2 = +&- sq. root of 12 x = 2 +&- 2(sq. root of 3)
If The product of x and negative 4 is 8 more than 2 added to negative 5 times that number what equation could be used to solve for x?
x*-4=8+(2-5*x) =-4x=8+2-x5 x*-4=8+(2-5*x) =-4x=8+2-x5 x*-4=8+(2-5*x) =-4x=8+2-x5
