Answer is no solution.
Wrong answer:
- Undefined
- x = 1
Explanation :
When obtaining the value of x = 1 by simplifying the fraction, if the value is plugged back into the equation it would be from
(x-1)(x-1)
————— = 0
(x-1)
to
(1-1)(1-1)
————— = 0
(1-1)
resulting in
0
— = 0
0
And the statement is simply false because anything divided by 0 is undefined.
Although, we cannot mark the answer as undefined since undefined simply means a value is not allowed whilst ‘no solution’ tells us there is no value that makes the equation true
Hence, answer to the question is NO SOLUTION

📐 AddMath CNY Question (Festive Edition)
During Chinese New Year, Ah Ma bought x boxes of pineapple tarts.
The total number of tarts is given by:
T(x) = x² + 5x
If Ah Ma bought 3 boxes, how many tarts does she have in total? 🍍🥠
Bonus: Don’t eat all the tarts before solving, okay? 😂

Ahhhh true ah, x² is Ah Ma’s promo deal 😆
Buy more boxes, extra tarts come for free 🥠🍍
But still… don’t be greedy, share with the family, or Ah Ma will stare at you like 👀

use differentiation and also completing the square method...to just recall ur f4c2 addmaths
Ah Ma’s festive cookie demand is modelled by the function:
y = x^2 e^x
where x is the number of days before Chinese New Year.
1️⃣ Find dy/dx
2️⃣ Find the stationary point(s)
3️⃣ Determine whether it is a maximum or minimum
Only true CNY addmath legends will survive this one 🥠📈

Q2. A box of festive cookies has a price modelled by the quadratic function:
f(x) = x^2 - 6x + 5
1️⃣ Factorise the expression.
2️⃣ Hence, find the values of x when f(x) = 0
f(x) = x^2 - 6x + 5

Q3. Two lanterns, A and B start to elevate from point O at the same time along a straight line in the same direction.
Lantern A travels a distance of p m in the first second and increases its distance travelled by q m for every subsequent second. If it travels a distance of 35 m in the 6th second and the total distance travelled in the first 10 seconds is 330 m, calculate the values of p and q. [4m]
