Question

2x²-3x=0
16x²=49
решите пожалуйста!!! ​

Answer 1

Ответ:

2x^2-3x=0

X(2x-3)=0

X=0

2x-3=0

X1=0

X2=2/3

16x^2=49

X^2=49/16

X=+-7/4

Объяснение:

Answer 2

$2x {}^{2} - 3x = 0$

$x(2x - 3) = 0$

$x = 0$

$x = \frac{3}{2}$

____________________________________________

$16x {}^{2} = 49$

$x {}^{2} = \frac{49}{16}$

$x {}^{2} - \frac{49}{16} = 0$

$16x {}^{2} - 49 = 0$

$(4x - 7)(4x + 7) = 0$

$x = \frac{7}{4}$

$x = - \frac{7}{4}$
