Question

guys please solve it​

Answer 1

$1.7 {x}^{3} - 6 + 2.4 {x}^{2} = 1.7 {x}^{3} + 2.4 {x}^{2} - 6$

$3.7 {x}^{2} + 2 + 2.4 {x}^{3} = 2.4 {x}^{3} + 3.7 {x}^{2} + 2$

$3.7 {x}^{2} + 2 + 2.4 {x}^{3} - (1.7 {x}^{3} - 6 + 2.4 {x}^{2} )$

$= 2.4 {x}^{3} + 3.7 {x}^{2} + 2 - (1.7 {x}^{3} + 2.4 {x}^{2} - 6)$

$= 2.4 {x}^{3} + 3.7 {x}^{2} + 2 - 1.7 {x}^{3} - 2.4 {x}^{2} + 6$

$= (2.4 - 1.7) {x}^{3} + (3.7 - 2.4) {x}^{2} + 2 + 6$

$= 0.7 {x}^{3} + 1.3 {x}^{2} + 8$

Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

To Do:

• Subtract (1.7x^3 - 6 + 2.4x^2) from (3.7x^2 + 2 + 2.4x^3)

Solution:

$:\longrightarrow (3.7x^2 + 2 + 2.4x^3) - (1.7x^3 - 6 + 2.4x^2) \\:\longrightarrow 3.7x^2 + 2 + 2.4x^3 - 1.7x^3 + 6 - 2.4x^2 \\:\longrightarrow 2.4x^3 - 1.7x^3 + 3.7x^2 - 2.4x^2 + 2 + 6 \\\bf{:\longrightarrow 0.7x^3 + 1.3x^2 + 8}$

Hope it helps!
