Answer:(-1, 5)
Step-by-step explanation:
Add X1 + X2 then divide by 2. Add Y1 + Y2 then divide by 2.
56 students represents 100 % and
X boys represent 34%,
so x= 56•34/100= 19.04 so approximately 19 boys
56-19= 37 girls signed up.
Now 37 girls represent 100% and 31 girls represent x % ,
So x= 31•100/37= 83.78% about 84% of the girls attended
Y = 15x + 35

The factored form of the given expression x² + x - 2 is ( x - 1 )( x + 2 ).
<h3>What is the factored form of the given expression?</h3>
Given the expression;
x² + x - 2
Consider the standard form ax² + bx + c compared to the given expression;
Now, we find a pair of integers whose product gives the value of c which is -2 and whose sum gives the value of b which is 1.
The integers are -1 and +2.
Check
-1 × 2 = -2
-1 + 2 = 1
Now, we write the factored form using these integers.
( x - 1 )( x + 2 )
Therefore, the factored form of the given expression x² + x - 2 is ( x - 1 )( x + 2 ).
