Answer 1

⇒First take out the highest common factor 2 form the quadratic equation and divide each and every term of that equation by that common factor.

⇒Factorise the equation and equate the factors of the equation to 0 and solve for the unknown variable x.

⇒Below are the steps on solving for the unknown variable.

`2(x^(2) -14x+49)=0 \\(2(x^(2) -14x+49))/(2) =(0)/(2) \\x^(2) -14x+49=0\\(x-7)(x-7)=0\\x-7=0\\x=7`
