Question

преоброзуйте выражение (5х-2)(х+1)-(5-2х) в многочлен стандартного вида

Answer 1

(5x-2)(x+1)-(5-2x)
5x^2+5x-2x-2-5+2x = 5x^2+5x-7

Answer 2

I can help you with your math problem. To transform the expression $(5x-2)(x+1)-(5-2x)$ into a polynomial of standard form, you need to follow these steps:

- First, use the distributive property to multiply the two binomials $(5x-2)(x+1)$. You get $5x^2+3x-2$. - Next, subtract the term $(5-2x)$ from the result. You get $5x^2+5x-7$. - Finally, arrange the terms in descending order of the degree of the variable $x$. You get $5x^2+5x-7$.

This is the final answer. The expression $(5x-2)(x+1)-(5-2x)$ is equivalent to the polynomial $5x^2+5x-7$ in standard form. I hope this helps.Ответь+подробно.+преоброзуйте+выражение+(5х-2)(х+1)-(5-2х)+в+многочлен+стандартного+вида
