Question;

14. What are the roots of x² + 6x - 8 = 0?

15. what are the solutions of the quadratic equation x²-12x + 35=0?

16.the roots of a quadratic equation are -5 and

3.Which of the following quadratic equation has these root?

Answer;

14.

$x = \frac{ - b+ \sqrt{b² - 4ac} }{2a}$

$x² + 6x - 8 = \green{\boxed{\tt \: 0}}$

$\tt \: a = \: \red{\boxed{\tt \: 1}}$

$\tt \: b = \pink{\boxed{\tt 6}}$

$\tt \: c = \blue{\boxed{\tt \: - 8}}$

$\green{\boxed{\tt \: x = \frac{ - 6 + \sqrt{6² - 4.1( - 8)} }{2.1} }}$

Sîmplîfy;

Eválûate the expónéñt
Múltiply the númbérs

$\blue{\boxed{\tt \: x = \frac{ - 6 + 2 \sqrt{17} }{2} }}$

Séparaté the eqûátiôns;

$x = \frac{ - 6 + 2 \sqrt{17} }{2}$

Sólve;

$\red{\boxed{\tt \: x = - 3 + \sqrt{17} }}$

$\tt \: x = - 3 - \sqrt{17}$

So the answer of number 14. is;

$\tt \: x = - 3 + \sqrt{17}$

15.

$\tt x = 7$

$\tt \: x = 5$

16.

$\tt \: x = - 5$
