22c^2-35c+12=-3c^2

解答

22 c^{2} - 35 c + 12 = - 3 c^{2}

解答

c = \frac{4}{5}, c = \frac{3}{5}

+1

十进制

c = 0.8, c = 0.6

求解步骤

22 c^{2} - 35 c + 12 = - 3 c^{2}

将

3 c^{2}

para o lado esquerdo

25 c^{2} - 35 c + 12 = 0

使用求根公式求解

c_{1, 2} = \frac{- ( - 35 ) \pm ( - 35 ) ^{2} - 4 \cdot 25 \cdot 12}{2 \cdot 25}

(- 35)^{2} - 4 \cdot 25 \cdot 12 = 5

c_{1, 2} = \frac{- ( - 35 ) \pm 5}{2 \cdot 25}

将解分隔开

c_{1} = \frac{- ( - 35 ) + 5}{2 \cdot 25}, c_{2} = \frac{- ( - 35 ) - 5}{2 \cdot 25}

c = \frac{- ( - 35 ) + 5}{2 \cdot 25} : \frac{4}{5}

c = \frac{- ( - 35 ) - 5}{2 \cdot 25} : \frac{3}{5}

二次方程组的解是:

c = \frac{4}{5}, c = \frac{3}{5}
