Question

Factorization write answer

Answer 1

5x²+12x+4

5x²+10x+2x+4

5x(x+2)+2(x+2)

(5x+2)(x+2)

Either, Or,

5x+2=0 x+2=0

x=-2/5 x=-2

Answer 2

(2)

↪ 5x² + 10x + 2x + 4

➡ 5x(x + 2) + 2(x + 2) = 0

➡ (x+ 2) (5x + 2) = 0

➡ x + 2 = 0 ; 5x + 2 = 0

➡ x = -2 ; x = -2/5

(3)

↪ 8x² + 6x + 4x + 3

➡ 8x² + 10x + 3 = 0

➡ 8x² + 4x + 6x + 3 = 0

➡ 4x(2x + 1) + 3(2x + 1) = 0

➡ (2x + 1) (4x + 3) = 0

➡ 2x + 1 = 0 ; 4x + 3 = 0

➡ x = -1/2 ; x = -3/4

(Example - 3)

↪ 3x² - 6x - 4x + 8 = 0

➡ 3x(x - 2) - 4(x - 2) = 0

➡ (x - 2) (3x - 4) = 0

➡ x - 2 = 0 ; 3x - 4 = 0

➡ x = 2 ; x = 4/3
