A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is 7x plus 8 equals 10x minus 2?

7x + 8 = 10x - 2 ∴ 3x = 10 ∴ x = 10/3


What is the value of x in 6-3x equals 5x-10x plus 12?

6x - 3x = 5x - 10x + 12 6x - 3x - 5x + 10x = 12 8x = 12 8x/8 = 12/8 x = 12/8 = 3/2 x = 1.5


Solve this equation Express fraction answers in lowest terms Check each solution Please show your work 3x minus 8 equals 7x plus 10 x equals?

3x-8=7x+10x 3x-8=17x -8 = 14x -4=7x -4/7


Which equals 3x2 - 10x - 8 when factored completely?

3x2 - 10x - 8 = (3x + 2) (x - 4)


How do you solve 3x2 plus 10x equals 8 by factoring?

3x² + 10x = 8 Rewrite as: 3x² + 10x - 8 = 0 The only way to get 3x² is 3x and x (3x + -- ) (x + --) The factors of 8 are {1 2 4 8} so the answers must be a pair of them. With 4 factors, and a negative sign (the -8), there are only 8 ways this can be written: (3x + 1)(x - 8) = 3x² - 23x - 8 (3x + 2)(x - 4) = 3x² -10x - 8 (almost) (3x + 4 )(x - 2) = 3x² - 8x - 8 (3x + 8)(x - 1) = 3x² +5x - 8 (3x - 1)(x + 8) = 3x² +23x - 8 (3x - 2)(x + 4) = 3x² + 10x -8 ◄ Success! (3x - 4)(x + 2) = 3x² +2x - 8 (3x - 8)(x + 1) = 3x² -5x - 8 Trial and error, error, error, is the key to this kind of problem. Seeing the -10x early can point you to see that maybe changing the signs can work. ■

What is the answer to 3xยฒ plus 10x equals 8?

3x² + 10x = 8 : 3x² + 10x - 8 = 0 Solving for the roots of a quadratic equation gives : x = [-10 ± √(100 + 96)] ÷ 6 = [-10 ± √196] ÷ 6 = [-10 ± 14] ÷ 6 So x = 4/6 = 2/3 and x = -24/6 = -4 x = 2/3 and x = -4

How do you solve 3x squared plus 10x- 8 equals 0?

3x2 + 10x - 8 = 0 3x2 + 12x - 2x - 8 = 0 3x(x + 4) - 2(x + 4) = 0 (3x - 2)(x + 4) = 0 So 3x - 2 = 0 or x + 4 = 0 so x = 2/3 or x = -4
