Step-by-step explanation:
(2x-12)+(1/2xy-10)
- (2×8-12)+(1/2×8×2-10)
- (16-12)+(8-10)
- 4+(-2)
- 4-2
- 2
Answer:
Step-by-step explanation:
= x - 5 ( x ≥ 3 )
( )² = ( x - 5 )²
x - 3 = x² - 10x + 25
x² - 11x + 28 = 0
(x - 4)(x - 7) = 0
= 7
= 4
Check the answer:
1). x = 7
= 7 - 2
√4 = 2
2 = 2
2). x = 4
= 4 - 5
1 = - 1 (False statement) ⇒ x = 4 is an extraneous solution.
