Question

Multiply : (x^2-7x+2) (x^2+5x-4)​

Answer 1

Step-by-step explanation:

= (x^2-7x+2) (x^2+5x-4)

= (x²-7x+2) (x²+5x-4)

= (x⁴+5x³-4x²-7x³-35x²+28x+2x²+10x-8)

= (x⁴ - 2x³ - 37x² + 38x - 8)

Answer 2

Answer:

Solution:

${ \implies{ \sf{( {x}^{2} - 7x + 2)( {x}^{2} + 5x - 4)}}}$

${ \implies{ \sf{ {x}^{4} + 5 {x}^{3} - 4 {x}^{2} - 7 {x}^{3} - 15 {x}^{2} + 28x + 2 {x}^{2} + 10x - 8 }}}$

${ \implies{ \sf{ {x}^{4} - 2 {x}^{3} - 17 {x}^{2} + 10x - 8 }}}$

Therefore,

• ${ \sf{ {x}^{4} - 2 {x}^{3} - 17 {x}^{2} + 10x - 8 \:is \: the \: Required \: Answer }} \:$
