Solve the follwing inequations by algebric and graphical methods. i) x^(2) – 8x + 15 gt 0 ii) 2x^(2) + 3x – 2 lt 0 iii) x^(2) - 4x + 5 gt 0 iv) 15x^(2) + 4x – 5 le 0

lim_(x to 3)(x^(3)-4x-15)/(x^(3)+x^(2)-6x-18)=…………………

Simplify : 15x-[8x^(2)+3x^(2)-{8x^(2)-(4-2x-x^(3))-5x^(3)}-2x]

2x^(4)15x^(3)+19x^(2)-15x+2=0 is a

Simplify : (15)/(2)xx(4)/(3)[6x^(2)-9x(x-bar(3-2x))]

Find the quotient and remainder when (7 + 15 x - 13 x^(2) + 5x^(3)) is divided by (4 - 3x + x^(2))
