t^2=3t

解

t^{2} = 3 t

解

t = 3, t = 0

解答ステップ

t^{2} = 3 t

3 t

を左側に移動します

t^{2} - 3 t = 0

解くとthe二次式

t_{1, 2} = \frac{- ( - 3 ) \pm ( - 3 ) ^{2} - 4 \cdot 1 \cdot 0}{2 \cdot 1}

(- 3)^{2} - 4 \cdot 1 \cdot 0 = 3

t_{1, 2} = \frac{- ( - 3 ) \pm 3}{2 \cdot 1}

解を分離する

t_{1} = \frac{- ( - 3 ) + 3}{2 \cdot 1}, t_{2} = \frac{- ( - 3 ) - 3}{2 \cdot 1}

t = \frac{- ( - 3 ) + 3}{2 \cdot 1} : 3

t = \frac{- ( - 3 ) - 3}{2 \cdot 1} : 0

二次equationの解:

t = 3, t = 0

(x-3)*(x+2)-(x-1)*(x-2)=(x+4)*(x-7)

(x - 3) \cdot (x + 2) - (x - 1) \cdot (x - 2) = (x + 4) \cdot (x - 7)

kx^2+(k-1)x-1=0

k x^{2} + (k - 1) x - 1 = 0

u(2u-1)a+(u-1)(2u-1)b+4u(1-u)c=0

u (2 u - 1) a + (u - 1) (2 u - 1) b + 4 u (1 - u) c = 0

0 = x^{2} - 10 x + 16
