Question

factories then polynomial = x^2+7x-60​

Answer 1

Answer:

x=−5; x=+12

Explanation:

Set x2+7x−60=0

Notice that (−5)×12=−60 and  12−5=7

⇒(x−5)(x+12)=0

x=−5; x=+12

Answer 2

Answer:

(x - 5)(x + 12)

Step-by-step explanation:

x² + 7x - 60

= x² + 12x - 5x - 60

= x(x + 12) - 5(x + 12)

= (x - 5)(x + 12)
