Question

Factorise 12x^+7x+1​

Answer 1

Step-by-step explanation:

$12 {x}^{2} + 7x + 1 \\ = 12 {x}^{2} + 4x + 3x + 1 \\ = 4x(3x + 1) + 1(3x + 1) \\ = (4x + 1)(3x + 1)$

Answer 2

${\huge{\red{\underline{\underline{\mathscr{\red{A}{\mathbb{\pink{N}{\mathtt{\blue{s}{\mathsf{\orange{w}{\mathrm{\purple{e}{\mathfrak{\green{r \: ࿐}}}}}}}}}}}}}}}}}$

12x²-4x-3x+1

= 4x(3x-1)-1(3x-1)

= (3x-1)(4x-1)
