Question 2.
\nFind the products
\ni. (5x + 8) 3x
\nii. (-3 pq)(-15 p3<\/sup>q\u00b2 – q3<\/sup>)
\niii. \\(\\frac{2 x}{5}\\left(3 a^{3}-3 b^{3}\\right)\\)
\niv. -x\u00b2(x – 15)
\nAnswer:
\ni. 5x . 3x + 8.3x = 15x\u00b2 + 24x<\/p>\n

ii. (- 3pq) (- 15p3<\/sup>q\u00b2 – q3<\/sup>)
\n= (- 3pq) (- 15p3<\/sup>q\u00b2) – (- 3pq)(q3<\/sup>)
\n= 45 p4<\/sup>q3<\/sup>\u00a0+ 3 pq4<\/sup><\/p>\n

iii. \\(\\frac{2 x}{5} \\times 3 a^{3}-\\frac{2 x}{5} \\times 3 b^{3}=\\frac{6 x a^{3}}{5}-\\frac{6 x b^{3}}{3}\\)<\/p>\n

iv. (-x\u00b2)x \u2013 (-x\u00b2) 15
\n= -x3<\/sup>\u00a0+ 15x\u00b2<\/p>\n

Question 3.
\nSimplify the following :
\ni. (2xy -xy) (3xy – 5)
\nii. (3xy\u00b2 +1) (4xy – 6xy\u00b2)
\niii. (3x\u00b2 + 2x) (2x\u00b2 + 3)
\niv. (2m3<\/sup> + 3m) (5m – 1)
\nAnswer:
\ni. 2x y (3xy – 5) – 2xy(3xy – 5) = 6x\u00b2y\u00b2 – 10xy – 6x\u00b2y\u00b2 + 10xy<\/p>\n

ii. 3xy\u00b2 (4xy – 6xy\u00b2) +1 (4xy – 6xy\u00b2) = 12 x\u00b2y3 – 18x\u00b2y4 + 4xy – 6xy\u00b2<\/p>\n

iii. 3x\u00b2(2x\u00b2 + 3) + 2x(2x\u00b2 + 3] = 6x4<\/sup> + 9x\u00b2 + 4x3<\/sup>\u00a0+ 6x<\/p>\n

iv. 2m3\u00a0<\/sup>(5m – 1) + 3m(5m – 1) = 10m4<\/sup> – 2m3\u00a0<\/sup>+ 15m\u00b2 – 3m<\/p>\n","protected":false},"excerpt":{"rendered":"
