Here's an example Its also call the 'ac' method:-
factor 2x^2 - 13x - 15
Multiply first coefficient by last number which is 2*-15 = -30
Now we need 2 factors of -30 which will when added give - 13:-
-15 and 2 looks good. So we can write:-
2x^2 - 13 x - 15
= 2x^2 + 2x - 15x - 15
factor by grouping first 2 and last 2 terms , we get:-
= 2x(x + 1) - 15(x + 1)
the x+1 is common so we have:-
(2x - 15)(x + 1) Answer
Hope this helps.
3/4 times 7/6 in simplest form = 0.875
You can factor -80 as
So, we have
The square root of a product is the product of the square roots:
Since 
and 
, we have
Answer:
DIABETES
Step-by-step explanation:
= 1 1/2 ÷ 2 / 3
= 3 / 2 ÷ 2 / 3
= 3 / 2 · 3 / 2
= 9 / 4
2.5 / 1 is your anwer : )
Answer:
square 10 to the 4th power but you have to divide it into 2 so it will be 10 to the 2nd power
hope this helps
