Solve and simplify 3. (y^2-7y-5)-(-3y^2+3y-4)

yKpoI14uk [10]

$(y^2-7y-5)-(-3y^2+3y-4)=y^2-7y-5-(-3y^2)-3y-(-4)\\\\=y^2-7y-5+3y^2-3y+4$

combine like terms

$=(y^2+3y^2)+(-7y-3y)+(-5+4)=\boxed{4y^2-10y-1}$

What are the coordinates of the vertex of the parabola y=x^2+2x-1

kozerog [31]

Y = x^2 + 2x - 1 = x^2 + 2x + 1 - 1 - 1 = (x + 1)^2 - 2
The vertex of a parabola given by y = a(x - h)^2 + k is (h, k).

Therefore, the vertex of y = (x + 1)^2 - 2 is (-1, -2)

How to answer this on descending powers of x please help pretty please

zheka24 [161]

Answer: 25x² - 64

Step-by-step explanation:

(5x + 8)(5x - 8)

= 5x(5x - 8) + 8(5x - 8)

= 25x² - 40x + 40x - 64

= 25x² + 0x - 64

= $\large\boxed{25x^2-64}$

NOTE: descending powers means the biggest exponent goes first, then the next biggest exponent, etc.

For example: x⁴ then x³ then x² then x then the number (which is actually x⁰)
