Question

12x²+61x+77, Find the factors of the given polynomial

Answer 1

12x^2 + 61x + 77

= 12x^2 + 28x + 33x + 77

= 4x ( 3x + 7) + 11(3x +7)

= (3x + 7)( 4x + 11)

Answer 2

Given Quadratic expression

12x² + 61x + 77

Splitting the middle term ,

= 12x² + 28x + 33x + 77

= 4x( 3x + 7 ) + 11( 3x + 7 )

= ( 3x + 7 )( 4x + 11 )

Therefore ,

12x² + 61x + 77 = ( 3x+7 )( 4x+11 )
