Question

Evaluate the expression given the replacement values.

−w^2−11uv+2v^2 for u=−1, v=8 and w=−3.

Answer 1

`\\ \sf\bull\longmapsto -w^2-11uv+1v^2`

`\\ \sf\bull\longmapsto -(-3)^2-11(1)(8)+1(8)^2`

`\\ \sf\bull\longmapsto -9-88+64`

`\\ \sf\bull\longmapsto -97+64`

`\\ \sf\bull\longmapsto -33`
