Mong mn giúp với ạ
G(x) =6x3-5x2+10x
G(-1) = 6.-13-5. -12+10. 1
a) -11
b) -21
Làm đi, mik tick nha ✔✔✔✔
\(a,G\left(-11\right)=6.\left(-11\right)^3-5.\left(-11\right)^2+10.\left(-11\right)\)
\(G\left(-11\right)=6.\left(-1331\right)-5.121+\left(-110\right)\)
\(G\left(-11\right)=-7986-605+\left(-110\right)\)
\(G\left(-11\right)=-8701\)

Mọi người giải giúp mk với ạ !!
Bài 1: Tìm x∈ Z , biết :
a , 9 - 25 = ( 7 - x ) - (25 + 7 )
b , x - ( 25 - x ) = x - 15
c, 14 - ( 27 - 13 ) = x - ( 3 - 14 )
Mn giúp mk với ạ !! Mk cảm ơn trước . Mk sẽ tick hết cho các bn !! ✔✔✔✔✔✔ 😍😊😘❤❤
a)-16=7-x-32=-25-x
x=-25+16=-9
b)x-25+x=x-15
2x-25=x-15
2x=x-15+25=x+10
x=10
c)14-27+13=x-3+14
0=x+11
x=-11
Tìm x biết

Bài 1 : tìm x∈Z .
a, 11-(15+11)=x-(25-9)
b, 2-x=17-(-5)
c, x-(17-x)=x-7
Mn giúp mk với ạ !!!! Mk cảm ơn nha !!!mk hứa sẽ tick cho các bn ✔✔
a, 11-(15+11)=x-(25-9)
\(\Leftrightarrow11-26=x-16\)
\(\Leftrightarrow x=-16-11+26\)
\(\Leftrightarrow x=-1\)
b, 2-x=17-(-5)
\(\Leftrightarrow2-x=22\)
\(\Leftrightarrow-x=22-2\)
\(\Leftrightarrow x=-20\)
c, x-(17-x)=x-7
\(\Leftrightarrow x-17+x=x-7\)
\(\Leftrightarrow x+x-x=-7+17\)
\(\Leftrightarrow x=10\)
Bài 1 :
a, Ta có : \(11-\left(15+11\right)=x-\left(25-9\right)\)
=> \(11-15-11-x+25-9=0\)
=> \(x=1\)
b, Ta có : \(2-x=17-\left(-5\right)\)
=> \(2-x=22\)
=> \(x=-20\)
c, Ta có : \(x-\left(17-x\right)=x-7\)
=> \(x-17+x-x+7=0\)
=> \(x=10\)
