44x² – x – 3

On comparing with standard quadratic equation that is

we have,

a = 44, b = – 1 and c = – 3

Now here,

Product a × c = – 132 = 44 × – 3

Factors of 132; 1 × 132; 2 × 66; 4 × 33;12 × 11

Sum should be b = – 1

From above factors ( – 12x – 11x)

will give – 1x sum

therefore – 1x is replaced by ( – 12x – 11x)

Now above eq. becomes

; taking x and – 9 common

(11x – 3)(4x – 1)
