Question

Rama wants to keep the dimensions of a rectangle which she drawn as secret and she prepared a quadratic expressions x square minus 7x plus 10. The zeros of that expression are the dimensions of the rectangle.Find the dimensions of the rectangle

Answer 1

$x^{2} +7x+10=0$
$x^{2} +5x+2x+10=0$
x(x+5)+2(x+5)=0 
x=-5 or x= -2

But since dimensions cannot be negative
dimensions are 5 and 2

Answer 2

x^2 - 7x + 10 = 0
x^2 - 5x - 2x + 10 = 0
x(x-5) -2(x-5) =0
(x-5)(x-2) = 0
x = 2 or x = 5

So dimension the rectangle is: length = 5 and breadth = 2
