a(x+b)-(x+a)^2=-x^2

解答

a (x + b) - (x + a)^{2} = - x^{2}

解答

x = - a + b; a \neq = 0

求解步骤

a (x + b) - (x + a)^{2} = - x^{2}

展开

a (x + b) - (x + a)^{2} : - x^{2} - a x - a^{2} + ab

- x^{2} - a x - a^{2} + ab = - x^{2}

将

a^{2}

到右边

- x^{2} - a x + ab = - x^{2} + a^{2}

将

ab

到右边

- x^{2} - a x = - x^{2} + a^{2} - ab

将

x^{2}

para o lado esquerdo

- a x = a^{2} - ab

两边除以

- a; a \neq = 0

x = - a + b; a \neq = 0

3.5 z - 2.7 z = - 6

12-(4y+8)=0.5(8y-16)

12 - (4 y + 8) = 0.5 (8 y - 16)

m + 14 - 2 m = - 8

solvefor x,3x-4y=-6

so l v e f or x, 3 x - 4 y = - 6

16+7x-5+x=11x-3-2x

16 + 7 x - 5 + x = 11 x - 3 - 2 x
