Answer 1

Given

2x³-4x²-5

3x²+4x-2

To find

Product

Solution

(2x³-4x²-5) (3x²+4x-2)

(2x³-4x²-5)(3x²)+(2x³-4x²-5)(4x)+(2x³-4x²-5)(-2)

(6x⁵-12x⁴-15x²+8x⁴=16x³-20x-4x³+8x²+10

(6x⁵-4x⁴-20x³-7x²-20x+10)

∴ 2x³-4x²-5 by 3x²+4x-2 :-

(6x⁵-4x⁴-20x³-7x²-20x+10)

Answer 2

Step-by-step explanation:

$\huge \bold { \red{\bold{Question}}}$

${2x}^{3} \: { - 4}^{ 2 } \: - 5 \: \times \: {3x}^{2} + 4x - 2$

$\huge \boxed { \red{\bold{Answer}}}$

${2x}^{3} - 16 - 5 \: \times \: {3x}^{2} + 4x - 2 \\ \\ (2 \times - 16 \times - 5 \times 3 \times 4 \times 2) \: ( {x}^{3} \times {x}^{2} \times x) \\ \\ (2 \times 240 \times 12 \times 2) \: ( {x}^{3} \times {x}^{2} \times x) \\ \\ (480 \times 24) \: ( {x}^{3} \times {x}^{2} \times x) \\ \\ (11520) \: ( {x}^{3} \times {x}^{2} \times x) \\ \\ 11520 \: {x}^{6}$
