" (ii) "7x-5=16

Solve : (i) 2x^(2)-7x=39 (ii) x^(2)=5x (iii) x^(2)=16

In the following write down the pairs which contain like terms: 3x,-7x (ii) 16x,16y

Add the following polynomials and find the degree of the resultant polynomial. (iii) f(x) = 16x^(4) - 5x^(2) + 9" " g(x) = -6x^(3) + 7x - 15

Solve: 7x-5=16

Solve the following equations. 7x - 5 = 16
