Answer 1

Answer:

${ \huge{ \sf{ \red{Question : }}}}$

• Product of 2x² + x - 5 and x² - 2x + 3

${ \huge{ \sf{ \green{Solution : }}}}$

$: { \implies { \sf{(2 {x}^{2} + x - 5)( {x}^{2} - 2x + 3)}}} \\ \\ : { \implies { \sf{2 {x}^{4} - 4 {x}^{3} + 6 {x}^{2} + {x}^{3} - 2 {x}^{2} + 3x - 5 {x}^{2} + 10x - 15}}} \\ \\ : { \implies{ \sf{2 {x}^{4} - 4 {x}^{3} + {x}^{3} - 6 {x}^{2} - 2 {x}^{2} - 5 {x}^{2} + 3x + 10x - 15 }}} \\ \\ : { \implies \bold{ \sf{2 {x}^{4} - 3 {x}^{3} - 13 {x}^{2} + 13x - 15 }}}$

∴ 2x⁴ - 3x³ - 13x² + 13x - 15 Is your answer

Answer 2

Answer:

(2x 2 +x−5)(x −2x+3)

:⟹2x 4 −4x 3 +6x 2 +x 3 −2x 2 +3x−5x 2 +10x−15

:⟹2x 4 −4x 3 +x −6x 2 −2x 2 −5x 2 +3x+10x−15

:⟹2x 4 −3x 3 −13x 2 +13x−15

∴ 2x⁴ - 3x³ - 13x² + 13x - 15 Is your answer
