`(2-50x ^(2))=` ?

The correct answer upto proper number of significant digits : (2.50 x 10^(-2) km) + (3.7 xx 10^2 cm) is :

to remove the 2^(nd) term of the equation x^4 -10 x^3 +35 x^2 -50 x^2 - 50 x+ 24=0 , diminish the roots by

int(dx)/((50+2x^(2)))

Foctorise : 50 x ^(2) - 2(x-2)^(2)

Factorise the following using appropriate identities . (i) 16x^(2)+24xy+9y^(2) (ii) 4y^(2)-4y+1 (iii) 4x^(2)-(y^(2))/(25) (iv) 18a^(2)-50 (v) x^(2)+5x+6 (vi) 3p^(2)-24p+36

Factorise the following using appropriate identities. (i) 16x ^(2) + 24xy + 9y ^(2) (ii) 4y ^(2) - 4y +1 (iii) 4x ^(2) - (y ^(2))/( 25) (iv) 18a ^(2) - 50 (v) x ^(2) + 5x + 6 (vi) 3p ^(2) - 24 p + 36

Factorise the following using appropriate identities. (i) 16x ^(2) + 24xy + 9y ^(2) (ii) 4y ^(2) - 4y +1 (iii) 4x ^(2) - (y ^(2))/( 25) (iv) 18a ^(2) - 50 (v) x ^(2) + 5x + 6 (vi) 3p ^(2) - 24 p + 36
