GIÚP MÌNH VỚI

Bài 1: Rút gọn rồi tính giá trị biểu thức:

a) A = 4x2.(-3x2 + 1) + 6x2.( 2x2 – 1) + x2 khi x = -1

b) B = x2.(-2y3 – 2y2 + 1) – 2y2.(x2y + x2) khi x = 0,5 và y = -1/2

Bài 2: Tìm x, biết:

a) 2(5x - 8) – 3(4x – 5) = 4(3x – 4) +11

b) 2x(6x – 2x2) + 3x2(x – 4) = 8

c) (2x)2(4x – 2) – (x3 – 8x2) = 15

Bài 3: Chứng tỏ rằng giá trị của biểu thức sau không phụ thuộc vào giá trị của biến x:

P = x(2x + 1) – x2(x+2) + x3 – x +3

Cho hình thang cân ABCD ( ab//cd) có góc A = góc 3D . tính các góc của hình thang cân

Tính các góc của hình thang cân , biết góc A= 3D

tìm x biết:

x(2x+1) +1/3−2/3x=0

ai làm hộ em câu này đi ạ

tìm x biết :

4x(x+1) = 8(x+1)

x(2x+1) +\(\dfrac{1}{3}-\dfrac{2}{3}x=0\)

x(x-4) +(x-4)² =0
