If using the method of completing the square to solve the quadratic equation x2 + 3x - 17 = 0, which number would have to be add
ed to complete the
square"?
1 answer:
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
