Since b2 is doubled by adding 3, b2 equals 3. 1/2 of that is b, hence b=1-1/2.
y=5
If we assume that it equals zero and you wish to solve for x, then the answer is:-x2 + 2x - 3 = 0x2 - 2x + 3 = 0x2 -2x + 1 = -2(x - 1)2 = -2x - 1 = ± √(-2)x = 1 ± i√2
you mean: y= -3x+1 y+x=-3+1 solve -3+1= -2 y+x = -2
3x-1 = 7 3x = 8X= 8/3 = 2+2/3
