Question

Solve the quadratic equation using factorisation method :
3x square =5+14x​

Answer 1

Answer:

x= +5 x= -1/3

Step-by-step explanation:

3x square - 14x -5 = 0

(mutilating first term into last term i.e. 3×5=15)

(factor of 15 are 15×1)

3x square -15x + 1x -5 = 0

3x(x -5) 1(x -5)

(x-5)(3x + 1)

x= +5 x= -1/3
