Multiply the factors and enter the resulting polynomial equation
Answer provided by our tutors
To expand the polynomial you first must click on 'Expand' tab, then type the expression and click 'Solve'.
In your case, you have typed an equation (there is "=" sign) that contains a variable 'x' so 'Algebrator' is returning the solution of the equation you typed: '(x+8)(x-7)=0'
If you wish to multiply the factors (expand the polynomial) you should type just '(x+8)(x-7)' and click 'Solve':
