If a and b are the roots of x^2+8x-5=0 If a and b are the roots of x^2+8x-5=0 find the values of a^3+b^3 and a^3b^3.write the equation whose roots are a^3 and b^3 (ab)^3 how can get -3375?please discribe cleary,thanks! 格战斗士_ww1年前2: echo780104 共回答了13个问题 | 采纳率100%

根据韦达定理：
x^2+8x-5=0的两根a,b满足
a+b=-8 ab=-5
a^3+b^3=(a+b)(a^2+b^2-ab)=(a+b)[(a+b)^2-3ab]=-632
a^3b^3=(ab)^3=-3375
所求方程为：x^2+632x-3375=0
