I didn't get all the part with the tiles, but here's the general answer:
given a polynomial
we have that is a factor of
if and only if k is a root of
, i.e. if
So, given the polynomial
We can check if is a factor by evaluating
:
So, is not a factor.
Similarly, we can evaluate to check if
are factors:
So, only is a factor of
The length of AB is (x + 4) cm and the values of a and be are a = 10, b = 4
A rectangle is a quadrilateral in which opposite sides are equal and parallel to each other. The area of a rectangle is:
Area = length * width
From the image:
Length of AB = x + 4
Length of BC = x + 6
The area of rectangle ABCD = Length of AB * Length of BC
28 = (x + 4)(x + 6)
x² + 10x + 24 = 28
x² + 10x = 4
Comparing with x² + ax = b gives:
a = 10, b = 4
Therefore the length of AB is (x + 4) cm and the values of a and be are a = 10, b = 4
