w^2+750-1504=0

解答

w^{2} + 750 - 1504 = 0

解答

w = 754, w = - 754

+1

十进制

w = 27.45906 \dots, w = - 27.45906 \dots

求解步骤

w^{2} + 750 - 1504 = 0

将

750

到右边

w^{2} - 1504 = - 750

将

1504

到右边

w^{2} = 754

对于

x^{2} = f (a)

解为

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

w = 754, w = - 754

因式分解-2x^2=7x-15

f a c t or - 2 x^{2} = 7 x - 15

4 x^{2} + 63 x - 16 = 0

solvefor x,f(x+h)=(x+h)^2

so l v e f or x, f (x + h) = (x + h)^{2}

solvefor a,a^2+b^2+c^2+(a+b+c)^2=2022^2

so l v e f or a, a^{2} + b^{2} + c^{2} + (a + b + c)^{2} = 202 2^{2}

X^{2} + 8 X + 16 = 0
