The roots of the equation x 2 - 8 x + 16 = 0 . · The correct Answer is:C · To find the roots of the quadratic equation x2−8x+16=0, we can follow these steps:. Apr 12, 2013 ... that is in the form: (x - h)^2 / a^2 - (y - k)^2 / b^2 = 1 for horizontal hyperbola or (y - k)^2 / a^2 - (x - h)^2 / b^2 = 1 for vertical ... 25x^2 – (x^2 + 8x + 16) = 0 25x^2 – x^2 – 8x – 16 = 0 24x^2 – 8x – 16 = 0. Now, since 0 / n = 0, we can divide both sides by the shared factor of 8 among ... x²+8x-3=0 x². /. Quad formula. 6 16 bo 1-. X. X = −8 ± √(8)² = 4(1)(-3). 2(1). X = −8 ± √76 = 14. -8. 2 jxz x²-6x-16=0. (x −8)(x+2)=0 x=8x=-2. X = −8 ± 2√19. =- ... We can now square root both sides to give: x+4=0. Now subtracting 4 from both sides gives x=-4. This means that for x^2+8x+16=0 we have found that x=-4. ... 2:” integration and its applications, including an introduction to ... (x) x . When x is near the value 1, what value (if any) is y near? While our ... Nov 10, 2014 ... Since |-4| = |4| = 4, we know that |x| = 4; this statement is sufficient. (2) SUFFICIENT: x2 = 8x – 16 x2 – 8x + 16 = 0 (x – 4)2 = 0 → V(x) = Ax² + B x² + 1/2 x - 5/ е-ра where 8,6 is solutions to a ara-1)+2 ... ⇒ x-8x + 17 = 0. =-8x=-17.
