Your answer is given below =》》》
Answer: -5 should be added.
Step by step -:::::
P(x) = X^2+7x -35
Then put the value of 3 in X,
I.e
P(3) = 3^2 +7*3-35
= 9 + 21 - 35
= -5
Therefore, -5 should be added to -35( REMEMBER ALWAYS PUT A SIGN OF SUBTRACT WHENEVER ADDED IS WRITTEN)

Step-by-step explanation:
STEPS OF CONSTRUCTION:
1.Draw line segment of length AB=8cm.
2. Draw any Ray AX making acute ∠BAX with AB
3. Draw a parallel to BY parallel to AX by making∠ABY=∠BAX.
