Answer:
Step-by-step explanation:
Given expression is,
(2x - 1)² + 2(2x - 1) = (2x - 1)(2x + 1)
To prove this identity we will take the left hand side of the equation and will prove equal to the right side.
(2x - 1)² + 2(2x - 1) = (2x - 1)(2x + 1)
4x² - 4x + 1 + 4x - 2 = (2x - 1)(2x + 1)
4x² - 1 = (2x - 1)(2x + 1)
(2x - 1)(2x + 1) = (2x - 1)(2x + 1) [Since a² - b² = (a - b)(a + b)]
Answer:
602
Step-by-step explanation:
Answer:
1=2p+3
2=
Step-by-step explanation:
Yes, good job! Since AB and CD are congruent, so are the angles
3x-6=5x+2
-3x -3x
-6 = 2x+2
-2. -2
-8=2x
-8/2 = x
x = -4
