" 12."quad 6(1-4x)+7(2+5x)=53

Solve each of the following equation and check your answers: (i) 6(1-4x)+7(2+5x)=53 (ii) 5(2-3x)-17(2x-5)=16

Solve: 6(1-4x)+7(2+5x)=53 . Check the result.

If f(x)=int_(1)^(x^(3))(dt)/(1+t^(4)), then f'(x) is equal (6x((1-5x^(2))^(12)))/((1+x^(12))^(12))) (ii) (6x((1+5x^(2))^(12)))/((1+x^(12))^(2))( (iii) -(6x((1-5x^(2))^(12)))/((1+x^(12))^(2)) (iv) none of these

From the sum of 6x^(4) - 3x^(3) + 7x^(2) - 5x + 1 and -3x^(4) + 5x^(3) - 9x^(2) + 7x - 2 subtract 2x^(4) - 5x^(3) + 2x^(2) - 6x - 8

The equation 4(5x^(2)-7x+2)=5(4x^(2)-6x+3) is

factorise i) 12x^(2)-7x+1 ii) 6x^(2)+5x-6

If Delta (x) =|{:(x^(2)-5x+3,2x-5,3),(3x^(2)+x+4,6x+1,9),(7x^(2)-6x+9,14x-6,21):}| = ax^(3) +bx^(2)+cx+d , then

If Delta (x) =|{:(x^(2)-5x+3,2x-5,3),(3x^(2)+x+4,6x+1,9),(7x^(2)-6x+9,14x-6,21):}| = ax^(3) +bx^(2)+cx+d , then

If Delta (x) =|{:(x^(2)-5x+3,2x-5,3),(3x^(2)+x+4,6x+1,9),(7x^(2)-6x+9,14x-6,21):}| = ax^(3) +bx^(2)+cx+d , then
