b2 + 8x + 7. 7 and 1 add up to be 8 and multiply to be 7. So therefore, it would be factored as: (b+1)(b+7)
(y - 7)(y - 2)
7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
Centre = (4, -3) Radius2 = (4 + 2)2 + (-3 + 7)2 = 36 + 16 = 52 Equation = (x - 4)2 + (y + 3)2 = 52 or x2 - 8x + y2 + 6x = 27
8x + 7
