Question

X ²-9x+20 factor as the product of binomials

Answer 1

ANSWER

• x²-9x+20 factor as the product of binomials is (x-4)(x-5).

GIVEN:

• x²-9x+20

TO FIND:

• Express the above expression in the product of binomials.

SOLUTION:

= x²-9x+20

= x²-4x-5x+20

= (x²-4x)+(-5x+20)

= x(x-4)-5(x-4)

= (x-4)(x-5)

x²-9x+20 factor as the product of binomials is (x-4)(x-5).

NOTE:

Some important formulas

(a+b)² = a²+b²+2ab

(a-b)² = a²+b²-2ab

(a+b)(a-b) = a²-b²

(a+b)³ = a³+b³+3ab(a+b)

(a-b)³ = a³-b³-3ab(a-b)

a³+b³ = (a+b)(a²+b²-ab)

a³-b³ = (a-b)(a²+b²+ab)

(a+b)² = (a-b)²+4ab

(a-b)² = (a+b)²-4ab
