Sagot :
Answer:
STEP1:Equation at the end of step 1
(((((32)+(2•(y2)))+5yx)-2y)+(5•(x2)))-3y2
STEP 2 :
Equation at the end of step2:
(((((32)+(2•(y2)))+5yx)-2y)+5x2)-3y2
STEP 3 :
Equation at the end of step3:
(((((32)+2y2)+5yx)-2y)+5x2)-3y2
STEP4:
Equation at the end of step4:
((((32 + 2y2) + 5yx) - 2y) + 5x2) - 3y2
STEP5:
Final result :
-y2 + 5yx - 2y + 5x2 + 9
the answer is
2x2- y2 - 5th - 2y
i right hope it's can help you
