Question

find the product of 3x²+4 and 2x²+3x+1​

Answer 1

Answer:

(3x²+4) × (2x²+3x+1)

=3x²(2x²+3x+1) +4(2x²+3x+1)

=6x⁴+9x³+3x² + 8x²+ 12x + 4

= 6x⁴+9x³+11x²+12x+4

Answer 2

$\large\bf\underline\purple{Answer}$

$(3 {x}^{2} + 4) \times (2 {x}^{2} + 3x + 1) \\ = 3 {x}^{2} (2 {x}^{2} + 3x + 1) + 4(2 {x}^{2} + 3x + 1) \\ = 6 {x}^{4} + 9 {x}^{3} + 3 {x}^{2} + 8 {x}^{2} + 12x + 4 \\ = 6 {x}^{4} + 9 {x}^{3} + 11 {x}^{2} + 12x + 4$
