SUMMARY

The discussion focuses on rearranging the quadratic equation s = ut + 1/2at² to isolate the variable t. Participants emphasize the importance of showing initial attempts to facilitate effective assistance. The equation is identified as a general quadratic equation, and two methods are suggested for solving it: completing the square and using the quadratic formula. The need to account for the term "ut" when isolating t² is also highlighted.

PREREQUISITES
  • Understanding of quadratic equations
  • Familiarity with the quadratic formula
  • Knowledge of completing the square technique
  • Basic algebraic manipulation skills
NEXT STEPS
  • Study the quadratic formula in detail
  • Practice completing the square with various quadratic equations
  • Explore applications of quadratic equations in physics
  • Review algebraic techniques for isolating variables
USEFUL FOR

Students, educators, and anyone seeking to enhance their understanding of quadratic equations and algebraic manipulation techniques.

can anyone help me rearrange
s = ut + 1/2at^2
to make t the subject.
If you could show the working it would be a real help.

You need to show us your attempt at work before we can offer tutorial help. Start by putting the 1/2at^2 all on one side, then isolate t^2, then what?

That's a general quadratic equation. You can either "complete the square" or use the quadratic formula to solve for t.

Berkeman, did you miss the "ut"? Getting t2 by itself won't help.
