Answer:
(x + 1)² = (2x)²
(1 + 1)² = (2(1))²
2² = 2²
4 = 4
(-1 + 1)² = (2(-13))²
(-12)² = (-26)²
Not true
x = -13 satisfies neither

Answer:
Points P, Q and R are collinear
Step-by-step explanation:
To prove that two or three points are collinear the slope of any two pairs of point have to be the same
From the given question
AR = AQ = CP = 2 units
BR = BP = CQ = 1 unit
For line AB we have ; AR , BR . hence slope of line = BR / AR = 1/2
For line BC we have ; BP , CP . hence slope of line = CP / BP = 2/1
For Line AC we have ; AQ , CQ . hence slope of line = CQ / AQ = 1/2
slope of Line AB = slope of Line AC hence points P, Q and R are collinear
