2x + y = 2<br><br> x – 2y = -4<br><br> what is x and y?
sergiy2304 [10]

Answer:

x = 0

y = 2

Step-by-step explanation:

2x + y = 2 (Multiply by 2)

x – 2y = -4

4x + 2y = 4

x – 2y = -4

5x = 0

x = 0

2x + y = 2

2(0) + y = 2

0 + y = 2

y = 2

lyudmila [28]

The factors of the specified polynomial by the grouping the polynomial and taking out GCF is,

(4x+5)(5x-3)

<h3>What is the factor of polynomial?</h3>

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

The factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result.

The given polynomial expression in the problem is,

20x^2+25x-12x-15

Factor the above polynomial by grouping as,

(20x^2+25x)+(-12x-15)

Factor the greatest common factor (GCF) from each group as,

5x(4x+5)-3(4x+5)\\

Write the polynomial as a product of binomials as,

5x(4x+5)-3(4x+5)\\(4x+5)(5x-3)

The above polynomial is written as a product of binomials.

Hence, the factors of the specified polynomial by the grouping the polynomial and taking out GCF is,

(4x+5)(5x-3)
