Answer:

See below.

Step-by-step explanation:

A difference of squares is a quadratic written in the form a^2-b^2. This form occurs naturally when distributing binomials.

(2x-3)(2x+3)\\4x^2-6x+6x+-\\4x^2 - 9\\(2x)^2 - 3^2

The difference of squares formula is

a^2-b^2 = (a-b)(a+b)

Example:

m^2 - 16y^2=(m-4y)(m+4y)

x^2-36 = (x-6)(x+6)

What is the discriminant of 3x2 - 10x = -2?<br> 76<br> 94<br> 106<br> 124
rewona [7]

Answer:

76

Step-by-step explanation:

Applying the formula to calculate the discriminant Δ=b2−4(a)(c)

Δ=b2-4(a)(c) with : a=3, b=−10, c=2

Δ=(−10)2−4⋅(3)⋅(2) = 100−24 = 76

The discriminant of the polynomial is equal to 76.

               10a² + 3a + 25 - 9a² + 6a - 5

- Group like terms

               (10a² - 9a²) + (3a + 6a) + (25 - 5)

- Simplify and result

                a² + 9a + 20
