Factor this trinomial. Your answer should consist of two binomials.
Sergeu [11.5K]
Y² + 8y - 33 :

Break  the expression  into groups for formula ax²+ bx+c :

= (y²- 3y) + (11y - 33 )

Factor y from y² - 3y =>  y (y - 3)

Factor out 11 from  11 y - 33 => 11 (y - 3)

= y ( y- 3 ) + 11 ( y - 3 )

Factor  out common  term (y - 3 ) :

= ( y - 3 ) ( y + 11 )

hope this helps!

Otrada [13]
f(x)=x^n;\ n\in\mathbb{Z^+}\\\\
function\ is\ even\ when\ f(-x)=f(x)\\\\function\ is\ odd\ when\ f(-x)=-f(x)\\\\a)\ f(x)\ is\ even\ when\ n\ is\ even:f(-x)=(-x)^n=x^n=f(x)\\\\b)\ f(x)\ is\ odd\ when\ n\ is\ odd:f(-x)=(-x)^n=-x^n=-f(x)
