Question

the expansion of X + 1 upon 3 and x minus 7 upon 3 is​

Answer 1

Explanation: In mathematics, an expansion of a product of sums expresses it as a sum of products by using the fact that multiplication distributes over addition.

x+1 / 3 = x-7/3

x+x = 7/3 - 1/3    

2x = 6/3 = 2/1 = 2

2x  = 2

x = 2/2

x = 1

Answer 2

Answer:

$x^{2} -2x-\frac{7}{9}$

Explanation:

$(x + \frac{1}{3})(x - \frac{7}{3} ) = x^{2} - \frac{7x}{3} + \frac{x}{3} - \frac{7}{9} = x^{2} -2x-\frac{7}{9}$
