Mathematics

6x^2 -x - 1

By degree: Quadratic

By number of terms: Trinomial

3x + 4

By degree: Linear

By number of terms: Binomial

By degree: Constant

By number of terms: Monomial

Step-by-step explanation:

Given

$(x - \frac{1}{2})(6x + 2)$

$(7x^2 + 3x) -\frac{1}{3}(21x^2 - 12)$

4(5x^2-9x+7)+2(-10x^2+18x-13)

Required

Simplify and categorize the result based on their degree and number of terms

Simplifying $(x - \frac{1}{2})(6x + 2)$

$x(6x + 2) - \frac{1}{2}(6x + 2)$

Open bracket

6x^2 + 2x - 3x - 1

6x^2 -x - 1

By degree: Quadratic

By number of terms: Trinomial

Simplifying $(7x^2 + 3x) -\frac{1}{3}(21x^2 - 12)$

Open bracket

$7x^2 + 3x -\frac{1}{3} * 21x^2 -\frac{1}{3}*- 12$

7x^2 + 3x -7x^2 + 4

Collect like terms

7x^2-7x^2 + 3x + 4

3x + 4

By degree: Linear

By number of terms: Binomial

Simplifying 4(5x^2-9x+7)+2(-10x^2+18x-13)

Open brackets

4*5x^2-4*9x+4*7+2*-10x^2+2*18x-2*13

20x^2-36x+28-20x^2+36x-26

Collect like terms

20x^2-20x^2-36x+36x+28-26

By degree: Constant

By number of terms: Monomial
