Work: Calculate the value of equation 1500×(490)^2/2-1/2×(1500-200)×(490-110/2)^2 .
Question type: Mathematical calculation
Solution:
1500×(490)^2/2-1/2×(1500-200)×(490-110/2)^2
=1500×490^2/2-1/2×(1500-200)×(490-110/2)^2
=1500×490^2/2-1/2×1300×(490-110/2)^2
=1500×490^2/2-1/2×1300×435^2
=1500×240100/2-1/2×1300×435^2
=1500×240100/2-1/2×1300×189225
=360150000/2-1/2×1300×189225
=180075000-1/2×1300×189225
=180075000-0.5×1300×189225
=180075000-650×189225
=180075000-122996250
=57078750
Answer:1500×(490)^2/2-1/2×(1500-200)×(490-110/2)^2=57078750
