Well if 5+5=10 adding 1 would give you 11. Or you could do 6+6=12 and then subtract 1. Both 5+5 and 6+6 are doubles facts.
Answer:
Step-by-step explanation:
To solve using completing square, we need to write the equation as x2+3x=17.
The next step is to add a number such that the square can be completed. The number must be equal to (b/2a)^2, so here it will be (3/2)^2 = 9/4
The equation then becomes x2+3x+(9/4)=17+(9/4).
Solving it further will get you the final answer
