<u>Answer</u>
9+√14
<u>Explanation</u>
To Rationalize the denominator of 5-√7/9-√14.
To rationalize this we multiply both the denominator and denominator by the conjugate of the denominator.
The denominator is 9-√14 and its conjugate is (9+√14).
(5-√7)/(9-√14) = (5-√7)(9+√14)/(9-√14)(9+√14)
= (5-√7)(9+√14)/(9²-14)
= (45 + 5√14 - 9√7 - √98)/(81-14)
= (45 + 5√14 - 9√7 - √98)/67
= (45 + 5√14 - 9√7 - 7√2)67
This is the rationalized expression.
The denominator is (9-√14) and its conjugate is (9+√14).
Let's solve your equation step-by-step.
-9 ÷ 3 + b = -1
Step 1: Simplify both sides of the equation.
<u>−9</u>
3
+b=−1
−3+b=−1
b−3=−1
Step 2: Add 3 to both sides.
b−3+3=−1+3
b=2
Answer:
b=2
