x² + 5x - 14 please give this it's urgent
Answers
Answer:
(x-2)(x+7)
Step-by-step explanation:
x²+5x-14
x²-2x+7x-14
(x²-2x)+(7x-14)
x(x-2)+7(x-2)
(x-2)(x+7)
Answer:
( x+2) (x-7)
Step-by-step explanation:
x^2 + 5x-14
x^2 + 5x - 14 = x^2 + 2x - 7x - 14
Working:
Here what i did is you break down the middle term to get.
here's trick, multiply (1)x with 14 you get = 14x
Now find the number that give you 14 by multiplying and 5x by adding or subtracting, therefore:
5x -14x
+2x-7x +2x . -7x
( note: . is also used to represent the sign of multiplication)
Now pair the two together:
(x^2 +2x) - (7x+ 14)
( notice how the 14 and 7x became positive that is because we take the minus or negative sign as common therefore they become positive)
Now take the common:
common in x^2 and 2x is x, and common in 7x and 14 is 7:
x ( x +2) -7 (x +2)
( x-7) ( x+2) or (x+2) (x-7)
--> doesn't matter which one you write first
Hope it helps! :)
Have a nice day
