9㎡-2m³+12m+4=0 所以m等于多少？

4㎡+12m - 1147=0等于多少

4㎡+12m-1147=0 可换算为:4㎡+12m+9=1156 (2m+3)²=1156 l2m+3l=34 当m为正数时,m=15.5 当m为负数时,m=-18.5

4(3 - 2m)² - 4m(3m - 2)=0 4m² - 12m+9 - 3m²+2m=0 m² - 10m+.

1) 4{(3-2m)²-m(3m-2)}=0 2) (3-2m)²-m(3m-2 3)9-12m+4m²-3m²+2m=0

4㎡ - 12m+12≥0等于多少

4㎡-12m+12≥0m²-3m+3≥0(m-3/2)²-9/4+3≥0(m-3/2)²+3/4≥0(m-3/2)²≥0(m-3/2)²+3/4≥3/4(m-3/2)²+3/4≥0,m可以取任意值

4m³+9mn²12m²n=

分解因式4m³+9mn²+12m²n=m(4m²+12mn+9n²)=m(2m+3n)²

9㎡+12m - 1=0

9㎡+12m-1=0(3m+2)(3m+2) -5 =0(3m+2)(3m+2) =53m+2=±√53m=-2±√5m=(-2±√5)/3

求解㎡ - 12m+23=0,m等于多少

m^2-12m+23=0(m-6)^2-36+23=0(m-6)^2=13即m-6=±√13所以m=6±√13

解关于y的一元一次方程:3y9 - 2m+12m=0

∵3y9-2m+12m=0是一元一次方程,∴9-2m=1,解得:m=4,∴原方程为3y+2=0,解得:y=-23.

m³ - 2m² - 4m+8等于多少

m方(m-2)+4(2-m)=(m方-4)(m-2)=(m+2)(m-2)(m-2) 望采纳谢谢

分解因式4m² - 12m+9

4m^3+16m^2-12m =-4m(m^2-4m+3) =-4m(m-1)*(m-3)

x² - 2mx - 2m - 4=0(m为已知数)

x²+2x=42mx²+4mx-12=0 所以2m(x²+2x)-12=0 所以2m乘以4-12=0 m=3/22m²+m=2乘以(3/2)平方+(3/2)=6
