Does anybody know any of these questions, please?...
1) Mandy is x years old
Her brother is 5 years older than Mandy
The product of their ages is 84
Show that x^2 + 5x - 84 = 0
(^2 meaning x "squared")
2)Solve the simultaneous equations
y=3x^2 (^2 meaning x "squared")
you must show your working out
Do not use a trial and improvement method.
Thanks any help would be appreciated!
