" 5."8x+4=3(x-1)+7

If 3 (5x-7) -4 (8x-13) =2 (9x-11)-17 , then the value of (7x-5)/(11x-9) is

If 3 ( 5x - 7) - 4 ( 8x - 13) = 2 ( 9x - 11) - 17, then the value of ( 7x - 5)/(11 x - 9) is

Check whether the following are quadratic equations : (1) (x-3)^(2)=x(2x-5) (2) (2x-3)(8x+1) = (4x+5)(4x-5) (3) (5x+3)(x-2)=(4x+3)(2x-1) (4) (2x+5)^(3)=8(x-1)^(3) (5) x^(2)+7x-8=x(x+5) (6) x^(3)+9x^(2)-7x+2=(x+3)^(3)

Fill in the blanks : (i)-4\ "x"7/9=7/9"x"\ ... (ii)5/(11)"x"(-3)/8=(-3)/8"x"\ .... (iii)1/2"x"\ (3/4+(-5)/(12))=1/2"x"\ ...+\ ..."x"(-5)/(12)\ (iv)(-4)/5"x"\ (5/7+(-8)/9)=((-4)/5"x" \ ...)+(-4)/5"x"(-8)/9

Simplify the following : 5x^(4) - 7x^(2) +8x - 1 +3x^(2) - 9x^(2) + 7 - 3x^(4)+11x - 2 +8x^(2)

3((7x+1)/(5x-3))-4((5x-3)/(7x+1))=11;x!=(3)/(5),-(1)/(7)

Differentiate the following functions: 7x^(6) + 8x^(5) - 3x^(4) + 11x^(2) + 6x+7

Obtain the differential of the following : (i) (x-1) (2x+5) (ii) (9x^(3)-8x+7)(3x^(2)+5)

if 4 x 9 x 3 = 4 and 5 x 3 x 1 = 3 then 8 x 10 x 7 = ?
