William multiplied (-2x+1-3y)(-0.5x) and got the wrong solution. Review his work and identify the step in which William made his first error.
Step 1 (-2x+1-3y)(-0.5x)
Step 2 (-0.5x)(-2x-3y+1)
Step 3 -0.5x(-2x)-0.5x(-3y)-0.5x(1)
Step 4 x^2+1.5xy-x
I think it’s step 4 but I’m getting a different answer please shoe me which step and how to find solution
