Question

Need help asap plz ill rate 5 star (only right answer please)

Answer 1

Answer:

$6x^2 -x - 1$

By degree: Quadratic

By number of terms: Trinomial

$3x + 4$

By degree: Linear

By number of terms: Binomial

$2$

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

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

$2$

By degree: Constant

By number of terms: Monomial
