Question

Find the preducts: qquad (A)-(3)/(5)x^(2)y times(1)/(3)xy^(2)​

Answer 1

Answer:

(i)

5x + 7x + (-6x)

= 5x + 7x -6x

= 6x

(ii)

35x +23x +−45x=9x +10x −12x15=7x15

(iii)

5a2b +( −8a2b) + 7a2b

= 5a2b − 8a2b + 7a2b

4a2b

(iv)

34x2 + 5x2+ (−3x2 ) + (−14x2)=34x2 − 14x2 + 5x2−3x2=12x2 + 2x2 = 52x2

(v) Collecting like terms and adding them:

x − 3y + 4z + y − 2x − 8z + 5x − 2y − 3z

= x- 2x + 5x - 3y + y - 2y + 4z - 8z - 3z

= 4x -4y -7z

(vi) Collecting like terms and adding them:

2x2 − 3y2 + 5x2 + 6y2 + (− 3x2 − 4y2)

= 2x2 + 5x2 − 3x2 − 3y2 +6y2 −4y2= 4x2 −y²
