The dimension of her garden whose area is g² + 14g + 40 is (g + 10) and (g + 4).
It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
Bailey writes the expression g² + 14g + 40
g² + 14g + 40
g² + 10g + 4g + 40
g (g + 10) + 4 (g + 10)
(g + 10)(g + 4)
The dimension of the factor is (g + 10) and (g + 4).
