father's age = y son's age = x y = 4x in 9 years time; y = 4x+9 son = x+9 product of their ages=70 (4x+9)(x+9)=70 4x^2 + 45x + 11 = 0 two likely numbers; 44*1=44 44+1=45 44 & 1 are factors 4x^2 + x +44x+11=0 factoring out x(4x+1)+11(4x+1)=0 x+11 & 4x+1 |

Re: Genuine: Solve This Maths And Win Airtime. by UtuokeAlcoholic: 5:42pm On Oct 01, 2020 |
Kylekent59: father's age = y son's age = x y = 4x 9 years ago, NOT in 9 years time; y = 4x - 9 son = x - 9 product of their ages=70 (4x - 9)(x - 9)=70 4x^2 - 45x + 11 = 0 two likely numbers; -44*-1=44 -44 -1 = -45 -44 & -1 are factors 4x^2 - x - 44x+11=0 factoring out x(4x - 1) - 11(4x - 1)=0 x - 11 = 0 or 4x - 1 = 0; x = 11 or x = 1/4 hence x = 11 is the valid ans |
Re: Genuine: Solve This Maths And Win Airtime. by Kylekent59: 5:46pm On Oct 01, 2020 |
UtuokeAlcoholic: I wanna use completing the square method. 4x^2 - 45x + 11 = 0 Divide all through by 4 x^2 - 45x/4 + 11/4 = 0 x^2 - 45x/4 + (-45/2*4) = - 11/4 + (-45/2*4)^2 (x - 45 / 8 )^2 = -11/4 + 2025/64 (x - 45 / 8 )^2 = -176 + 2025 / 64 (x - 45 / 8 )^2 = +/- √( 1849/64) (x - 45 / 8 )^2 = +/- 43/8 x = 43/8 + 45/8 or = 43/8 -45/8 x = 88/8 or -2/8 x = 11 or -1/4 age cannot be negative, hence x = 11 years |

Kylekent59:You made a mistake at the bolded -43/8 + 45/8 = 2/8 not -2/8 |
