Question

Find the product: (5x – 6 + 2x2 ) and (3+4x)​

Answer 1

Step-by-step explanation:

Find the product: (5x – 6 + 2x2 ) and (3+4x)

(5x-6+2*2) (3+4x)

(5x-6+4)(3+4x)

(5x-2)(3+4x)

5x*3 +5x*4x-2*3-2*4x

15x+20x^2-6-8x

20x^2-15x-8x-6

20x^2-23x-6

Answer 2

$= (5x - 6 + 2 {x}^{2} )(3 + 4x)$

$= 3(5x - 6 + 2 {x}^{2} ) + 4x(5x - 6 + 2 {x}^{2} )$

$= 15x - 18 + 6 {x}^{2} + 20 {x}^{2} - 24x + 8 {x}^{2}$

$= 15x - 24x + 26 {x}^{2} + 8 {x}^{2} - 18$

$= - 9x + 34 {x}^{2} - 18$
