x^2+1=3-x^2

解答

x^{2} + 1 = 3 - x^{2}

解答

x = 1, x = - 1

求解步骤

x^{2} + 1 = 3 - x^{2}

将

1

到右边

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

将

x^{2}

para o lado esquerdo

2 x^{2} = 2

两边除以

2

x^{2} = 1

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

x = 1, x = - 1

1 = 1

- 1 = - 1

x = 1, x = - 1

t^{2} - 3 t - 2 = 0

solvefor x,(x-m)^2=6-m

so l v e f or x, (x - m)^{2} = 6 - m

(2x+15)(9+2x)-(15)(9)=100

(2 x + 15) (9 + 2 x) - (15) (9) = 100

x^2+8((-8-3x)/4)=0

x^{2} + 8 (\frac{- 8 - 3 x}{4}) = 0

(x+6)^2+3(5x-6)=-2(x^2+x)

(x + 6)^{2} + 3 (5 x - 6) = - 2 (x^{2} + x)
