Given x 2-4x + 3 = 0, find the value of 2 (x-1) 2-4 (1 + x)
2 (x-1) 2-4 (1 + x) = 2x2-4x + 2-4-4x = 2x2-8x-2 ∵ x2-4x + 3 = 0 ∵ x2-4x = - 3, ∵ original formula = 2 (x2-4x) - 2 = 2 × (- 3) - 2 = - 8
What is the value of 0-3 & # 178; (- 3) ^ 3 - (- 4))?
0-3²÷（（-3） ^3-(-4))
=-9÷（-27+4)
=-9÷（-23）
=9/23
0-3²÷（（-3） ^3-(-4))
=-9÷（（-27）+4))
=-9÷（-23）
=9/23
0-9÷（-27+4）=-9÷（-23）=9/23

How to solve that the square of x plus 4x equals one
x²＋4x=1
x²＋4x＋4=5
(x＋2)²=5
x＋2=±√5
x=－2±√5
Yao Yan, Hello!
x²+4x=1
x²+4x+4=5
(x+2)²=5
x+2=±√5
X = - 2 + √ 5 or x = - 2 - √ 5
Formula method: a * x ^ 2 + b * x + C = 0, if the equation has a root, the root is x = (- B ± √ △) / (2 * a).
X^2+4X-1=0
If △ = 20 > 0, the equation has two unequal real roots,
The solution is x = - 2 + √ 5 or x = - 2 - √ 5

When the square of x-4x + 1 = 0, find the square of X-1 / X - (1 + X-1 / 2)
X-1 / X squared - (1 + X squared-1 / 1)
=4+4/((x-1)+1/(6x-1)
When x = 1 + √ 3,
The original formula = 4 + 4 / √ 3 + 1 / (6 √ 3-5) = 4 + 4 √ 3 / 3 + (6 √ 3 + 5) / 83
When x = √ 3-1
Original formula = 4-4 / √ 3 + 1 / (6 √ 3-7) = 4-4 √ 3 / 3 + (6 √ 3 + 7) / 59
