i. −7x2+15xy
ii. 4a2b2+3a
iii. 15xy+11z2
Answers
Answer:
i)-29xy
ii)11aab
iii)0
Step-by-step explanation:
i) -7×2+15xy
= -14+15xy
= -29 xy
ii)4a2b2+3a
= 8ab+3a
= 11aab
iii) 15xy+11z2
= it is unlike fractions so it can't added
Given : -7x² + 15xy
To find : tree diagram
Solution:
Expression Terms Factors
-7x² + 15xy -7x² -7 , x , x
15xy 15 , x , y
15 is constant hence not factored
