`4x-[3x-(1-5x)-6{8-3(2x+7)]}`

Simplify the following 9x-[8-(3-7x)-3[5x-3(4-2x)}]

lim_(xrarroo)((2x-3)(4x-5))/((5x-6)(6x-7)) is equal to

Let's find the roots of the equations 5x - (4x - 7) (3x - 5) = 6 - 3(4x - 9) (x - 1)

Simplify: 4x^(3)-2x^(2)+5x-1+8x+x^(2)-6x^(3)+7-6x+3-3x^(2)-x^(3)

Solve : (3)/(5)(4x-9) - (5)/(4)(3x-8) = 5-(7)/(10)(2x-1) .

(2x-(7-5x))/(9x-(3+4x))=7/6

Subtract: 7x^(4)-5x^(3)+4x^(2)+3x-3 from 6x^(4)-4x^(3)-8x^(2)-2x+7

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)

Value of lim_(x rarr0)(ln(1+2x-3x^(2)+4x^(3)))/(ln(1-5x+6x^(2)-7x^(3))) is
