Question

find the area of rectangle whose length and breadth are the roots of the quadratic equation x square-6x+8=0

Answer 1

The answer is 8 . ........

Answer 2

Answer:

8 units square.

Step-by-step explanation:

x^2 - 6x + 8 = 0

x^2 - 4x - 2x + 8 = 0

x (x - 4) - 2(x - 4) = 0

(x-4)(x-2) = 0

x = 4 ; x = 2.

Area of rectangle = l*b = 4*2 = 8.
