Answer» i) 2xy, 7xy 7xy – 2xy = (7 – 2) xy = 5xy ii) 5a², 10a² 10a -5a = (10-5) a²= 5a² iii) 12y, 3y 3y – 12y = (3 – 12)y = -9y iv) 6x²y, 4x²y 4x²y – 6x²y = (4 – 6) x²y = -2x²y v) 6xy,-12xy (-12xy) – 6xy = (-12 – 6) xy = -18xy

Subtract the first term from the second term. i) 2xy, 7xyii) 5a2, 10a2iii) 12y, 3yiv) 6x2y, 4x2yv) 6xy, -12xy

Answer»

i) 2xy, 7xy

7xy – 2xy = (7 – 2) xy = 5xy

ii) 5a², 10a²

10a -5a = (10-5) a²= 5a²

iii) 12y, 3y

3y – 12y = (3 – 12)y = -9y

iv) 6x²y, 4x²y

4x²y – 6x²y = (4 – 6) x²y = -2x²y

v) 6xy,-12xy

(-12xy) – 6xy = (-12 – 6) xy = -18xy
