Решите уравнения различными . -24=-2y²+2y 9y²-12y-5=0

(3p-5)(p+1)=-4

3x(x-2)=24

m(m+10)=2

- 24 = - 2y² + 2y

12 = y² - y

12 - y² + y = 0

- 12 + y² - y = 0

y² - y - 12 = 0

y² + 3y - 4y - 12 = 0

y × ( y + 3 ) - 4( y + 3 ) = 0

( y + 3 ) × ( y - 4 ) = 0

y + 3 = 0

y - 4 = 0

y = - 3

y = 4

______________________________

9y² - 12y - 5 = 0

9y² + 3y - 15y - 5 = 0

3y × ( 3y + 1 ) - 5(3y + 1 ) = 0

( 3y + 1 ) × ( 3y - 5 ) = 0

3y + 1 = 0

3y - 5 = 0

______________________________

( 3p - 5 )( p + 1 ) = - 4

3p² + 3p - 5p - 5 = - 4

3p² - 2p - 5 = - 4

3p² - 2p - 5 + 4 = 0

3p² + p - 3p - 1 = 0

p × ( 3p + 1 ) - ( 3p + 1 ) = 0

( 3p + 1 ) × ( p - 1 ) = 0

3p + 1 = 0

p - 1 = 0

3x( x - 2 ) = 24

x × ( x - 2 ) = 8

x² - 2x = 8

x² - 2x - 8 = 0

x² + 2x - 4x - 8 = 0

x × ( x + 2 ) - 4( x + 2 ) = 0

( x + 2 ) × ( x - 4 ) = 0

x + 2 = 0

x - 4 = 0

x = - 2

x = 4

______________________________

m(m+10)=2

m² + 10m = 0

m² + 10m - 2 = 0
