Answer:

-7 and 14

Step-by-step explanation:

x^2-7x=98

subtract 98 so that the equation equals 0

x^2-7x-98=0

factor out the equation finding numbers that subtract or add to 7, which would be 14 and 7 as they multiply to 98 and subtract to 7.

(x+7)(x-14)=0

solve for zero

x+7=0 -> x= -7

x-14=0 -> x= 14
