Question

решите: 4m(степень) 2-24m+9

Answer 1

$4 {x}^{2} - 24x + 9 = 0$
$d = {b}^{2} - 4ac = { (- 24)}^{2} - 4 \times 4 \times 9 = 576 - 144 = \sqrt{432}$

$x1 = \frac{ - b + \sqrt{432} }{2a} = \frac{24 + \sqrt{432} }{8}$
$x2 = \frac{ - b - \sqrt{432} }{2a} = \frac{24 - \sqrt{432} }{8}$

Answer 2

4x²-24x+9=0
x=-(-24)±√(-24)²-4*4*9/2*4
x=24±√576-144/8
x=24±432/8
x=24±12√3/8
x=24+12√3
x=24-12√3/8
x=6+3√3
x=6-3√3
x₁=6-3√3/2; x₂=6+3√3/2
