    In completing the square method ,,,, For example = 2x² - 5x + 3 = 0 ,, so we need to remove coefficient 2 from x².,, Then ,, 2 ( x² - 5x/2 + 3/2 ) = 0 /2 = 0,, = x² - 5x/2 + 3/2 = 0 ,,,, Second step - x² - 5x/2 = - 3/2 ,, Third step - x² - 5x/2 + [ 5/2 ]² - [5/2 ]² = - 3/2 ,,,,use the formula of( a - b )². Forth step -[ x² - 5/4 ]² - [5/2]² = - 3/2,,,, =[ x - 5/4 ]² = - 3/2 +[ 5/2]²,, = [ x - 5/4]² = - 3/2 + 25/4,,,, = [ x - 5/4 ]² = - 24 + 25 / 16 =( [ x² - 5x/2]² = 1/16),,,,root of 16 is 4 then,,,, = x - 5/4 = ± root 1/4,,,, = Firstly take positive integer. + 1/4 . Then negative. - 1/4. x = 1/4 + 5/4 = 1 + 5 / 4 = 6/4 = 3/2 ,,= X = 2. = X = 2 . = x = - 1/4 + 5/4 = - 1 + 5 /4 = 4/4 = 1. = X = 1. [Answer is X =1 and X = 2 ],, Hence proved ,, It is not important because this method is deleted in syllabus Thank you,, Shubham Saxena

    Given , sin A = 3/5 We know, sin A= perpendicular /hyp. Therefore, P= 3 and H=5 Using Pythagoras theorem, H sq. = P sq. +B sq. or, 25 = 9 + B sq. or, B = 4 Therefore, cos A=B/H = 4/5 And, tan A = P/B = 3/4

    1Thank You

    Shubham Saxena ???? 5 years, 2 months ago

    Use square trigonometric identity = cos2A + sin2A = 1 TanA = sinA/ cosA = 3/5/4/5 = 3/4.

    Sorry, the above answer is wrong. The line should be divided in the ratio 1:2 . The formula is the same. The answer should be (0,1).

    1Thank You

    Souvig Saha 5 years, 2 months ago

    As the line segment is trisected, therefore, it is divided in the ratio 1:3. Following the section formula --- {1(-6)+3*3} /1+3 , {1*5+3(-1)}/1+3. are the points of trisection. Therefore, the points of trisection are : (3/4 , 1/2)
