-43
-44
-45.
-43 + -45 is -88
The P right there you put = -3/7 after it
Answer:
Sol: In this question, firstly we have to make the first bracket as a complete square of the second bracket. This we can by adding 2.x.1/x which is equivalent to 2. Then the equation becomes:
6(x2 + 1/x2 +2) – 5(x + 1/x) = 50 { 38 + 6*2)
⇒ 6(x2 + 1/x2 +2) – 5(x + 1/x) – 50 = 0
Now put x + 1/x = y
⇒ 6y2 -5y -50 = 0
⇒ (2y +5)(3y-10)= 0
⇒ y=-5/2 or 10/3
As x is positive therefore, x + 1/x =10/3
On solving further you will get as x=3 or 1/3
Since - 5 is less than -4, hence the point (0, 0) is a solution to the inequality y-5<3x-4
<h3>Solution to inequality expression</h3>
Inequality are equations not separated by an equal sign. Given the inequality
y-5<3x-4
Check if (0, 0) is a solution
0 - 5 < 3(0) - 4
-5 < -4
Since - 5 is less than -4, hence the point (0, 0) is a solution to the inequality y-5<3x-4
