Factorize Quadratics Polynomials

Factor the following polynomial:-

x² + 2x - 24

• (x - 2) (x + 5)

• (x - 4) (x + 6)

• (3 x + 2) (x + 1)

Factorize the following expression:-

20a2 – 45b2

• 5(a+3b)(a-3b)

• (a + 8)(a – 8)

• 5(2a + 3b)(2a – 3b)

Factorise the following trinomials:-

x² + 7x +10

• (x + 5)(x -2)

• (x + 5)(x + 2)

• 2x(x-5)

Factorize the following trinomials:-

x² + 5x + 6

• (x + 2)(x + 3)

• (x - 2)(x -3)

• x(x+2)(x-3)

Whenever you are factoring

ANY polynomial,

what do you ALWAYS do first?

• Look for a GCF and take it out

• Use XBox Method

• Use Factor By Grouping

• Cry

Select all the polynomials that can be factored using the XBox method

AFTER THE GCF IS TAKEN OUT

• Linear

• Quadratic

• Cubic

• Quartic

• Any Degree Polynomial

(x+1) (x+1) is a factor of

• x²+1-2x

• x²+2x+1

• x²-2x+1

• 2x+1-x
