What must be added to $2x^2-3xy+5y^2$ to get $x^2-xy+y^2$?

How much is $a+3b-4c$ greater than $3a-2b+c$?

If the simplification of $\left(-5a{b}^3{c}^7\right).(-6a^3{b}^2{c}^{10})$ gives $k{a}^4{b}^5{c}^{17}$, then find the value of $k$

If the simplified value of $\left(8x{y}^2\right)\left(y^3{z}^2\right)\left(-\frac{1}{2}{x}^4{z}^3\right)$ is $k{x}^5{y}^5{z}^5$, find the value of $k$

Simplify: $18a^3{b}^4{c}^5÷9a^3{b}^3{c}^6$

Simplify: $\left(12a^2{b}^{2}c+16abc\right)÷4ab$

Simplify: $\left(2x-3\right)\left(x+5\right)-(x^2-3x+2)$

What will be the remainder when $6x^5+4x^4-27x^3-7x^2+27x+\frac{3}{2}$ is divided by $\left(2x^2-3\right)?$
