Sagot :
Answer:
(x - 3/2)² - 21/4 = 0
Step-by-step explanation:
2x² - 6x = 15
2x² - 6x - 15 = 0
(2x² - 6x + 18/4) - 15 - 18/4 = 0
2(x² - 3x + 9/4) - (60-18)/4 = 0
2(x - 3/2)² - 42/4 = 0
2[(x - 3/2)² - 21/4] = 0
(x - 3/2)² - 21/4 = 0
Answer:
(x - 3/2)² - 21/4 = 0
Step-by-step explanation:
2x² - 6x = 15
2x² - 6x - 15 = 0
(2x² - 6x + 18/4) - 15 - 18/4 = 0
2(x² - 3x + 9/4) - (60-18)/4 = 0
2(x - 3/2)² - 42/4 = 0
2[(x - 3/2)² - 21/4] = 0
(x - 3/2)² - 21/4 = 0
