solvefor a,h=ax^2+7x+c

解答

求解

a, h = a x^{2} + 7 x + c

解答

a = \frac{h - 7 x - c}{x ^{2}}; x \neq = 0

求解步骤

h = a x^{2} + 7 x + c

交换两边

a x^{2} + 7 x + c = h

将

7 x

到右边

a x^{2} + c = h - 7 x

将

c

到右边

a x^{2} = h - 7 x - c

两边除以

x^{2}; x \neq = 0

a = \frac{h - 7 x - c}{x ^{2}}; x \neq = 0

solvefor m,5m+n=8

so l v e f or m, 5 m + n = 8

solvefor x,3x+y+6=0

so l v e f or x, 3 x + y + 6 = 0

log_{10}(2^{-3})= 1/8

lo g_{10} (2^{- 3}) = \frac{1}{8}

solvefor x,2x-6y=5

so l v e f or x, 2 x - 6 y = 5

a x - b = c x - d
