Answer 1

Ответ:

$1. x^{2} -2x = 0\\x(x-2)=0\\x = 0\\x = 2\\\\2. y^{2}+4y = 0\\y(y+4)=0\\y1=0\\y2=-4\\\\3. 4x^{2} -3x=0\\x(4x-3)=0\\x1=0 \\x2=\frac{3}{4} \\\\4. -9y^{2}-8y=0\\-y(9y+8)=0\\y1=0\\y2=-\frac{8}{9} \\\\5. 2x^{2} =3\\x^{2} =\frac{3}{2}\\x = \frac{\sqrt{3} }{\sqrt{2} } = \frac{\sqrt{3} }{\sqrt{2} } * \frac{\sqrt{2} }{\sqrt{2} }= \sqrt{\frac{6}{2} } \\\\6. 16-x^{2} =0\\x^{2} =16\\x1=4\\x2=-4$
