first a sub tract trail from both sides of the secret and it becomes 12 X squared minus seven years minus 12. Vehicle zero. Then we can identify the confessions of this career. A equals 12 because minor 7th and say equals miners trip. Next we substitute A B. And C. With their values. Into this form. The denominator is two times 12 And the numerator is seven plus on minors. The square road of minor seven squared -4 times 12 times -12, Which equals seven plus miners The square root of 625 or 24 what she calls seven plus miners 25/24. So the first solution is 4th, 3rd, 2nd Solutions, miners 3/4
