Using Section Formula Prove That The Three Points 4 6 10 2 4 6 And 14 0 2 Are Collinear

When you take the square root of both sides of the equation, you need a plus or minus sign before the right side to show that the positive value squared equals (xb/2a)² and that the negative value squared equals (xb/2a)²The square root of x², for example, does not equal x but rather equals the absolute value of x, so the right side may be positive or negativeJust like we expressed the geometric proof of expansion of quadratic formula we prove the expansion of (a b) 3 the expansion is (ab)³ = a³ 3a²b 3ab² b³2 29 if a ib=0 wherei= p −1, then a= b=0 30 if a ib= x iy,wherei= p −1, then a= xand b= y 31 The roots of the quadratic equationax2bxc=0;a6= 0 are −b p b2 −4ac 2a The solution set of the equation is (−b p 2a −b− p 2a where = discriminant = b2 −4ac 32
