25.25x^(2)+20x+7=0

In the following,determine whether the given quadratic equations have real roots and if so, find the roots 6x^(2)+x-2=0 (ii) 25x^(2)+20x+7=0

Find the roots of each of the following equations, if they exist, by applying the quadratic formula: 25x^(2)+30x+7=0

Solve the following equations using Sreedhar Acharya's formula : 25x^(2)-30x+7=0

The function f: [0,∞] to R given by f(x) = 25x^(2) + 10x – 7 is not invertible. What will be the codomain of the function f to make it invertible.

10x^(2)-20x+1=0

In the following, determine whether the given quadratic equations have real roots and if so, find the roots (i) 6x^2+x-2=0 (ii) 25 x^2+20 x+7=0

Factorize: (x+2)(x^(2)+25)-10x^(2)-20x

Without solving , comment upon the nature of roots of each of the following equations : (i) 7x^(2)-9x+2=0 (ii) 6x^(2)-13x+4=0 (iii) 25x^(2)-10x+1=0 (iv) x^(2)+2sqrt(3)x-9=0 (v) x^(2)-ax-b^(2)=0 (vi) 2x^(2)+8x+9=0

2x^(2) - 13x+20 = 0, 2y^(2) - 7y + 6 = 0
