Where the techniques of Maths
are explained in simple terms.

Algebra - Factorisation - Completing the Square (monic quadratics).
Test Yourself - Test 1.


Complete the square on each of these expressions. 1. 2.
3. 4. y2 - 10y - 9
5. m2 - 14m -15 6. t2 - 20t - 6

Complete the square to solve the following quadratic equations.

 7. 8.
9. 10. d2 = 4d + 5
11. t2 + 14t + 13 = 0 12. z2 + 6z = 91
Complete the square to solve the following equations having an odd coefficient for the second term: 13. 14.
15. 16. m2 = 11m - 30
17. J2 + 13J + 8 = 0 18. x2 - 23x - 5 = 0

Note: Use you calculator to simplify adding the fractions together

AND ALSO

for determining if there are square factors in the term on the RHS in Q 17 and Q 18 especially
Factorising with a (Casio) calculator.
