Answer 1

Answer:

I think 98 I did it but I forgot

Answer 2

$x^2-15x+54=0$

$\bold \red{x = \frac{ - b \underline{ + } \sqrt{ {b}^{2} } - 4ac}{2a}}$

a=1

b=-15

c=54

$\bold \red{x = \frac{ - ( - 15) \underline{ + } \sqrt{ {( - 15)}^{2} } - 4 \times 1 \times 54}{2 \times 1}}$

$\bold \red{x = \frac{ 15 \underline{ + } 3}{2}}$

$\bold \red{x = \frac{ 15{ + } 3}{2}}$

$\bold \red{x = \frac{ 15{ - } 3}{2}}$

$\bold \red{x = 9}$

$\bold \red{x = 6}$
