The process of finding two or more expression whose sum is the given expression is called factorisation

• True

• False

Factorisation is the reverse of division

• True

• False

Factor of 35x²y²-21xy is:

• 7xy(5xy-3)

• 7x²y(5xy+3)

• 2xy²(17.5xy+10.5x)

The factorisation of polynomials include the following methods:

• Taking Out Common Factors

• Grouping

• Algebraic Identities

• Factors of trinomials

Factorise 24x³-32x²

• 2x² (12x²-16x)

• 8x²(3x-4)

• 4x²(6x-8x)

Factorisation by grouping is possible only if the given binomial contains an even and odd number of terms

• True

• False

a²+2ab+b²=

• (a+b)²

• a²-b²

25a²-64b²=

• (5a+8b²)(5a-8b)

• (5a+8b)(5a-8b)

• (5a+8b)²

16y³-4y=

• 4y²(4y²-1)

• 2y²(8y²+8)

• 4y[(2y)²-1²]

• 4y(2y+1)(2y-1)

(7x²+14x)÷(x+2)=

• 7x²+2

• 7

• x

• 7x
