Question
Read each sentence to find out whether there is any
error in it. The error, if any, will be in one part of the sentence. Mark the part with the error as your answer. If there is no error, mark "No Error" as your answer. (Ignore the errors of punctuation).Solution
The correct answer is E
I. 14p2 – 135p + 81 = 0
II. 7q2 – 65q + 18 = 0
I. x3 = 1728
II. y2 – 15y + 56 = 0
I. 7x² + 27x + 18 = 0
II. 19y² - 27y + 8 = 0
Equation 1: x² - 250x + 15625 = 0
Equation 2: y² - 240y + 14400 = 0
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between x and y.
I. x
I. 3p² + 13p + 14 = 0
II. 8q² + 26q + 21 = 0
I. x ² + 5 x + 6 = 0                Â
II. y²+ 7 y + 12= 0
...Roots of the quadratic equation 2x2 + x – 528 = 0 is
l. x2 - 16x + 64 = 0
II. y2Â = 64
If x + 1/x = 3, find x² + 1/x².
