Respuesta :
I factored and got:
(x - 10) (x + 2)
so I set each to 0....and got 10 and -2
(x - 10) (x + 2)
so I set each to 0....and got 10 and -2
The factors of the given quadratic equation will be ( x - 10 ) ( x + 2 ).
What is a quadratic equation?
The polynomial having a degree of two or the maximum power of the variable in a polynomial will be 2 is defined as the quadratic equation and it will cut two intercepts on the graph at the x-axis.
Here we are having an equation:-
= x² - 8x - 20
= x² - 10x + 2x - 20
= x ( x - 10 ) + 2 ( x - 10 )
= ( x - 10 ) ( x + 2 )
Therefore the factors of the given quadratic equation will be ( x - 10 ) ( x + 2 ).
