Question
Although he had prepared well (1)/ for the interview,
(2)/ he could not answered (3)/ several of the technical questions (4) Read the sentence to find out whether there is any grammatical or idiomatic error in it. The error, if any, will be in one part of the sentence. The letter of that part is the answer. If there is ‘No error’, the answer is (5). (Ignore errors of punctuation, if any).Solution
"Could not answered" should be "could not answer," as "could" is followed by the base form of the verb.
I. 35x² - 51x + 18 = 0
II. 30y² + 17y – 21 = 0
If α, β are the roots of the equation x² – px + q = 0, then the value of α2+β2+2αβ is
...I. 2x2 - 9 x + 9 = 0
II. 2y2 - 7 y + 3 = 0
I. 2y² - 3y – 14 = 0
II. 3x² - 7x + 4 = 0
I: x² - 10x + 21 = 0
II: 4y² - 16y + 15 = 0
If x² + 2x + 9 = (x – 2) (x – 3), then the resultant equation is:
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 41x + 400 = 0
Equation 2: y² - 41y + 420 = 0
The equation q2 - 17x + C = 0, has two roots ‘x’ and ‘y’ such that (x – y) = 7. Find an equation which is equal to thrice of the gi...
1.3wx = 40 – wy
2. b2 = 2b + p
3. d2 + d = q
Now, observe the given conditions:
One root of equation...
(i) 2x² – 12x + 16 = 0
(ii) 2y² – 20y + 48 = 0
