Solve the following quadratic equations by factorisation method `:`
(i) `x^(3) - 4x + 3 = 0` (ii) `m^(2) - m - 2 = 0 ` (iii)` p^(2) + 9p + 20 =0 `
(iv)` q^(2) + q-12= 0 ` (v) `y^(2) + 2y - 35= 0 ` (vi)` 3x^(2) + 5x= 0 `
(vii) `x^(2) - 7x + 12=0` (viii) ` x^(2) - 7x - 18 = 0 `

Explanation

(i) 3,1 are the roots ( OR x=3, x =1 ) (ii) 2,-1 are the roots
(iii) -4,-5 are the roots (iv) -4, 3 are the roots
(v) -7,5 are the roots (vi) 0,`- (5)/(3)` are the roots
(vii) 3,4 are the roots (viii) 9,-2 are the roots
