Answer:
Step-by-step explanation:
→ x = 2 + 3/4
→ x = 2/1 + 3/4
→ x = 2*4/1*4 + 3*1/4*1
→ x =8/4 + 3/4
→ x = 11/4
→ putting value of x :
→ x² - 6x
→ (11/4)² - 6(11/4)
→ (11*11/4*4) - 6(11/4)
→ 121/16 - 66/4
→ 121/16 - [66÷2/4÷2 = 33/2]
→ 121/16 - 33/2
→ 121*1/16*1 - 33*8/2*8
→ 121/16 - 264/16
→ -143/16
