In this worksheet, you must use trial and improvement to solve equations.
Solve a2 = 54 giving the answer to 1 decimal place.
Try a value you think will be close to the answer.
|a =||a2 =|
|7||49||This is too small. Try a bigger value.|
|8||64||This is too big. Try between 7 and 8.|
|7.5||56.25||Now let's try half way. Too big. Try a smaller number.|
|7.35||54.02||Let's try half way between 7.3 and 7.4. Too big.|
The value of a is closer to 7.3 than 7.4
Answer to 1 decimal place is a = 7.3
