solvefor b,f=b^2xc

解答

求解

b, f = b^{2} x c

解答

b = \frac{f}{x c}, b = - \frac{f}{x c}; x c \neq = 0

求解步骤

f = b^{2} x c

交换两边

b^{2} x c = f

两边除以

x c; x c \neq = 0

b^{2} = \frac{f}{x c}; x c \neq = 0

对于

x^{2} = f (a)

解为

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

b = \frac{f}{x c}, b = - \frac{f}{x c}; x c \neq = 0

solvefor x,x+2y-1/3 (3x-2)=-4/3

so l v e f or x, x + 2 y - \frac{1}{3} (3 x - 2) = - \frac{4}{3}

8 + 12 x = 15 x - 19

solvefor p,p+q=7

so l v e f or p, p + q = 7

(a+5)(a+3)=a^2+2a+5

(a + 5) (a + 3) = a^{2} + 2 a + 5

3 x + 7 = 10
