The area of the rectangular painting is given by the trinomial x squared + 4x - 21 what are the possible dimensions of the painting use factoring
To find the dimensions of the painting, we need to factor the trinomial x^2 + 4x - 21.
The factored form is given by:
x^2 + 4x - 21 = (x - 3)(x + 7)
From the factored form, we see that the dimensions of the painting can be x - 3 and x + 7.
Therefore, the possible dimensions of the painting are:
Length: x + 7
Width: x - 3
In general, these dimensions will depend on the value of x.
