3x + 2x - 8x + 2x = -x
4x2+8x+3 ------> (2x+3)(2x+1)
Let the required number be equal to x According to the given equation 2/3 of x= 8(-x) 2x/3= -8x 2x/3+(-8x)=0 2x/3-8x=0 2x/3-24x/3=0 -21x/3=0 -21x=0 x=0/-21 x=0 Hence the number would be 0.
2x-3=10x+21 2x-3-2x=10x+21-2x -3=8x+21 -3-21=8x+21-21 -24=8x -3=x
4
-8x
x = 9.
8x-9 -2x plus 11 when solved mathematically is equal to 6x + 2.
-6
It equals 8x+12
2x
3x + 2x - 8x + 2x = -x
The answer is No Solution, Assuming the problem is [ x2 = 8x - 90 ]: x2 = 8x - 90 [ or, 2x = 8x - 90 ] 10x = (-90) x = (-9) So, lets plug in "x". 2(-9) = 8(-9) - 90 (-18) = (-72) - 90 (-18) = (-162) And thus, there is no solution.
8x-2x+4x=10x
If that's - 8x - 5, the answer is (2x + 1)(2x - 5). If that's + 8x + 5, it gets ugly in a hurry.
The given expression can be simplified to: 10x -5
4x2+8x+3 ------> (2x+3)(2x+1)
