solvefor x,maxz=2x^1+x^2

解答

求解

x, ma x z = 2 x^{1} + x^{2}

解答

x = 0, x = ma z - 2

求解步骤

ma x z = 2 x^{1} + x^{2}

交换两边

2 x^{1} + x^{2} = ma x z

将

ma x z

para o lado esquerdo

2 x + x^{2} - ma x z = 0

因式分解

2 x + x^{2} - ma x z : x (x - ma z + 2)

x (x - ma z + 2) = 0

使用零因数法则： If

ab = 0

then

a = 0

or

b = 0

x = 0 or x - ma z + 2 = 0

解

x - ma z + 2 = 0 : x = ma z - 2

二次方程组的解是:

x = 0, x = ma z - 2

(10^{7.24}*0.1)x^2-((0.2)/2)=0

(1 0^{7.24} \cdot 0.1) x^{2} - (\frac{0.2}{2}) = 0

- 3 x^{2} - 2 x = - 3

L(2000)=2v^2+50v+10

L (2000) = 2 v^{2} + 50 v + 10

x[x+8(x-6)]=7-[5-(2x+5)]

x [x + 8 (x - 6)] = 7 - [5 - (2 x + 5)]

solvefor y,3=e^{-2x}(2y^2+2x^2+2x+1)

so l v e f or y, 3 = e^{- 2 x} (2 y^{2} + 2 x^{2} + 2 x + 1)
