2x2 - 5x + 6 = ?
x = -1
(2 x (-1)2) - (5 x -1) + 6 = ?
(2 x 1) - (-5) + 6 = ?
2 + 5 + 6 = 13
1
-1 plus 1 = 0 plus 1 =1
a+a=1 2a=1 a=1/2
i have no clue what the answer is
x = 5, y = -1
That factors to (a + 1)(a + b) a = -1, -b b = -a
A = 1, B = 9
8+-1= 7 x=-1
If: x+1+2x = 1x+5 Then: x = 2
y=5
wel i cant explain how i did this but the answer is -1/7
It equals 2 over 8.
