Work: Calculate the value of equation 2^2*(-1/2)+3*2*(-1/2)^2 .
Question type: Mathematical calculation
Solution:
2^2*(-1/2)+3*2*(-1/2)^2
=2^2*(-0.5)+3*2*(-1/2)^2
=2^2*(-0.5)+3*2*(-0.5)^2
=4*-0.5+3*2*(-0.5)^2
=4*-0.5+3*2*0.25
=-2+3*2*0.25
=-2+6*0.25
=-2+1.5
=-0.5
Answer:2^2*(-1/2)+3*2*(-1/2)^2=-0.5
