Answer:
![x(x+5)=x^2-3x+8](https://tex.z-dn.net/?f=x%28x%2B5%29%3Dx%5E2-3x%2B8)
Step-by-step explanation:
There are infinite cases of equations with exactly one real solution. To create something worth the space, this one should suffice
![x(x+5)=x^2-3x+8](https://tex.z-dn.net/?f=x%28x%2B5%29%3Dx%5E2-3x%2B8)
Operating
![x^2+5x=x^2-3x+8](https://tex.z-dn.net/?f=x%5E2%2B5x%3Dx%5E2-3x%2B8)
Simplifying
![5x=-3x+8](https://tex.z-dn.net/?f=5x%3D-3x%2B8)
Joining like terms
![8x=8](https://tex.z-dn.net/?f=8x%3D8)
Solving
x=1
Testing the result
![1(1+5)=1^2-3(1)+8=>6=6](https://tex.z-dn.net/?f=1%281%2B5%29%3D1%5E2-3%281%29%2B8%3D%3E6%3D6)

Step-by-step explanation:
The element at row i column j in the product is the dot-product of row i of the first matrix and column j of the second matrix. For example, row 2 column 1 of the product is ...
(row 2) · (column 1)
[3, -2, 4] · [2, 7, 1] = (3)(2) +(-2)(7) +(4)(1) = 6 -14 +4 = -4
The attachment shows the complete product matrix. It is convenient to let a spreadsheet or graphing calculator do the tedious repetitive arithmetic.
This answer is pretty simple.
