Question

if the area of a rectangle is given by 9x^2-3x-20.Find length and breadth of rectangle

Answer 1

the value of x can be 5/3 and -4/3.....the question is incomplete though....you did not mention the relation between length and breadth

Answer 2

Step-by-step explanation:

9x2-3x-20                                                                          ab is -180

9x2+12x-15x-20                                                                   a+b=-3

3x(3x+4)-5(3x+4)

(3x+4)(3x-5)

X=-4/3 or x=5/3
