Answer:
129-14 is 115 than minus 6 than add 12
Step-by-step explanation:
To solve this equation simply find 2 numbers that multiply to give -4 and add also to give 3, these numbers are 4 and -1. Since 4 • -1 = -4 and 4 + -1 = 3.
X^2 + 3x - 4 = 0
(X - 1)(X + 4) = 0
X = -4 and X = 1 in ascending order.
Answer:
The sign is negative
Step-by-step explanation:
Given
Required
Determine the sign
The expression can be split into 3 factors
If x > 0 then x is positive and If y < 0 then y is negative
So, the expression becomes:
<em />
Leave only signs
So, we have:
So, we have:
<em>Hence, the sign of the expression is negative</em>
<em></em>
Take for instance;
The expression would be:
-- negative
