X² - 6x + 7 = 0

(x-3)² = 2
The amount each boy receives from the R2100 is R420, R700 and R980 respectively
<h3>How to find ratio</h3>
Total amount = R2100
Ratio = 3 : 5 : 7
Total ratio = 3 + 5 + 7
= 15
First boy = 3/15 × 2100
= 0.2 × 2100
= R420
Second boy = 5/15 × 2100
= 0.33333333333333 × 2100
= R700
Third boy = 7/15 × 2100
= 0.46666666666666 × 2100
= R980
