A(x)=x((288-2x)/2)

解答

A (x) = x (\frac{288 - 2 x}{2})

解答

x = 0, x = - A + 144

求解步骤

A (x) = x (\frac{288 - 2 x}{2})

将

x (\frac{288 - 2 x}{2})

para o lado esquerdo

A x - x \frac{288 - 2 x}{2} = 0

因式分解

A x - x \frac{288 - 2 x}{2} : x (A - 144 + x)

x (A - 144 + x) = 0

使用零因数法则： If

ab = 0

then

a = 0

or

b = 0

x = 0 or A - 144 + x = 0

解

A - 144 + x = 0 : x = - A + 144

二次方程组的解是:

x = 0, x = - A + 144

(2x+1)(4x^2-2x+1)-1=1.6x^2(5x-2)

(2 x + 1) (4 x^{2} - 2 x + 1) - 1 = 1.6 x^{2} (5 x - 2)

x^{2} + 6 x + 1 = - 2 x + 1

2 p^{2} - 7 p = 5

3 (x - 4)^{2} = 27

x^{2} - 20 x + 90 = - x
