Answer:
that is the solution to the question
Answer:
x= 20 x =-5
Step-by-step explanation:
x^2 – 15x – 100 = 0.
What two numbers multiply to -100 and add to -15
-20 * 5 = -100
-20 +5 = -15
(x-20) (x+5) =0
Using the zero product property
x-20 =0 x+5 = 0
x= 20 x =-5
30,000
the way you can solve this is by removing all numbers in front of the selected number(in this case, 2 should be removed) then change all numbers behind to 0.
Answer:
false all the quadratic equations cannot be solved by factorising there is also graphical method to get the solution
