Write the following quadratic equations ...

Write the following quadratic equations in standard from and then write the values of a,b and c `:`
(i) `x^(2) -9 = 13 x ` (ii) `2x^(2) = 3x `
(iii) `x+ ( 5)/( x) = - 3 ` (iv) ` ( x+ 4 ) ( x-10) = 0 `

Text Solution

Verified by Experts

`x^(2) - 13x - 9 = 0 , a = 1 , b= - 13, c = - 9 `
(ii) ` 2x^(2) - 3 x + 0 = 0 , a = 2 , b = - 3,c = 0 `
(iii) ` x^(2) + 3 x + 5 = 0 , a = 1 , b = 3 , c = 5 `
(iv)` x^(2) - 6x - 40 =0, a = 1 , b = - 6 , c = - 40`
