Question

solve for x x^2-14x+49÷x^2-49=3÷7​

Answer 1

FIRST WE WILL SOLVE THE NUMERATOR OF RHS

WHICH IS

X^2-14X+49

=X^2-7X-7X+49

=X(X-7)-7(X-7)

=(X-7)(X-7)

NOW WE WILL SOLVE

DENOMINATOR OF RHS

X^2-49

=(X+7)(X-7)

SO

X^2-14X+49/X^2-49=3/7

(X-7)(X-7)/(X+7)(X-7)=3/7

X-7/X+7=3/7

7(X-7)=3(X+7)

7X-49=3X+21

7X-3X=21+49

4X=70

X=70/4

X=35/2

X=17.5
