Factorise 2x²-9x+10 (this must be put in two brackets)

galben [10]

Find both roots :
$\Delta=81-80=1$ hence $r=\frac{9\pm1}4=\frac{5}2\text{ or }2$

Thus it is $2(x-\frac{5}2)(x-2)$

Hayley borrowed $1,854 from her parents. She agreed to repay them in equal installments throughout the next 18 months. How much

Serggg [28]

Answer: $ 618

Step-by-step explanation:

Money borrowed = $1,854

Total months taken to repay = 18 (Number of installments)

Money paid per month = $\dfrac{\text{Money borrowed}}{\text{Number of installments}}$

$=\dfrac{1854}{18}=\$103$

Now , money paid in 1 year = 12 x $ 103 =$ 1236 [1 year = 12 months ]

After a year , Haley still owe = $1,854 - $ 1236= $ 618

Hence, Haley still owe her parents $618 after a year .
