How do you solve algebra

it is gard to explain so i will give you link you can get help there.

Step-by-step explanation:

FORMULAS

a (b + c) = ab + ac

(a + b)2 = a2 + 2ab + b2

(a − b)2 = a2 − 2ab + b2

(a + b)(a − b) = a2 − b2

Making Groups ( factorize four terms)

2x² - 2x + 5x - 5

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

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

Evaluation of algebraic expressions

The process of replacing the variables in an expression with the numerical values and simplifying it is known as evaluating an algebraic expression. Following order of operation is used to evaluate an algebraic expression;

1. Perform the operations inside a parenthesis first

2. Then exponents

3. Then multiplication and division, from left to right

4. Then addition and subtraction, from left to right

Hope this will help you if you need more help about algebra free to ask i will try !

because algebra is big enough

we need more info to solve this

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
