1.
solve by factorising:
t^2-12=4t
2.
solve giving the answers correct to one dp;
2x^2 - 6x + 3 = 0
3.
A parabola has formula y = (x - 8)^2 + 11
a) write down the coordinates of the turning point
b) write down the equation of the axis of symmetry
1. t^2-12 = 4t subtract 4t from both sides
t^2 - 4t - 12 = 0 factor
(t - 6) (t + 2) = 0 set each factor to 0
t - 6 = 0 → t = 6 and t + 2 = 0 → t = -2
3. a. (8 , 11)
b. x = 8
