Question

solve the following quadratic equation by factorisation method x+35/x=12,x is not equals to 0
​

Answer 1

Answer:

x + 35/x = 12

x + 35/x - 12 = 0

Multiply by x

x(x) + x(35/x) - 12x = 0

x^2 - 12x + 35 = 0

x^2 - 7x - 5x + 35 = 0

x(x-7) - 5(x-7) = 0

(x-5) (x-7) = 0

x-5=0 OR x-7=0

x=5 OR x=7

x= 5 or 7
