Answer:
x = -1 and y = 6
Step-by-step explanation:
using x = -b/2a
x = -4 / 2(2)
x = -1
y = 2(-1)² + 4(-1) + 8
y = 2 - 4 + 8
y = 10 - 4
y = 6
Final result :
4x3yz2 • (3x - 2y2)
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "z2" was replaced by "z^2". 4 more similar replacement(s).
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(((12•(x4))•y)•(z2))-((23x3•y3)•z2)
Step 2 :
Equation at the end of step 2 :
(((22•3x4) • y) • z2) - 23x3y3z2
