Firstly, use the factor theorem to determine one factor. Substitute factors of 24 into the equation, beginning at plus or minus 1 and then increasing. The first factor found will be -2, therefore (x+2) is...

Kenny originally had £3200 After a year, he had £3360 £3360 - £3200 = £160 160/3200 = 0.05 0.05 x 100 = 5% Therefore, a 5% interest rate was applied to Kenny's account

Using factorisation, first we would have to look at the factors that multiply to make the last term, (-14). We know that they are +/- 7 and -/+2, and +/- 14 and -/+ 1, respectively. Now we have listed the...

5x-7x < -6+3 => -2x < -3 => x > 3/2

6x^2 - 10x + 12x - 20

6x^2 + 2x - 20
