Question

if the area of rectangle is 4x to the power of 3 +4x - 3 then its possible dimensions are:

a. (2x-3) (2x+1)
b. (2x-1) (2x-3)
c. (3x+1) (2x-3)
d. (3x-1) (2x+3)

Answer 1

Answer:

i think ques should be 4x to the power of 2 and not 3.

Step-by-step explanation:

and then the answer will be (a.)

area of rectangle =length×breadth

therefore,

4x^2+4×-3 = 4x^2+6x-2x = 2x(2x+3)-1(2x+3) = (2x+3)(2x-1)
