can you ask me questions based on the math lesson, "identities"?
Answers
Answer:
Subtract the following polynomials.
(i) (7x + 2) from (-6x + 8)
(ii) 3xy + 5yz – 7xz + 1 from -4xy + 2yz – 2xz + 5xyz + 1
(iii) 2x2y2– 3xy + 4 from 4x2y2 + 10xyAdd the following polynomials.
(i) x + y + xy, x – z + yx, and z + x + xz
(ii) 2x2y2– 3xy + 4, 5 + 7xy – 3x2y2, and 4x2y2 + 10xy
(iii) -3a2b2, (–5/2) a2b2, 4a2b2, and (⅔) a2b2Simplify the following expressions:
(i) (x + y + z)(x + y – z)
(ii) x2(x – 3y2) – xy(y2 – 2xy) – x(y3 – 5x2)
(iii) 2x2(x + 2) – 3x (x2 – 3) – 5x(x + 5)Calculate the area of a rectangle whose length and breadths are given as 3x2y m and 5xy2 m respectively.Identify terms and their coefficients from the following expressions:
(i) 6x2y2 – 9x2y2z2+ 4z2
(ii) 3xyz – 8y
(iii) 6.1x – 5.9xy + 2.3yUsing suitable algebraic identity, solve 10922
