Q. What is the value of the expression below when z=5 z=5 ?\newlinez2−z+6 z^{2}-z+6 \newlineAnswer:
  1. Substitute zz with 55: First, we need to substitute the value of zz with 55 in the expression z2−z+6z^{2}-z+6. So, we replace zz with 55 and calculate the new expression. 52−5+65^{2} - 5 + 6
  2. Calculate zz squared: Now, we calculate the square of 55, which is 5×55 \times 5.52=255^{2} = 25
  3. Subtract 55 from zz squared: Next, we subtract 55 from 2525.25−5=2025 - 5 = 20
  4. Add 66 to the result: Finally, we add 66 to the result from the previous step.\newline20+6=2620 + 6 = 26
