help in math?

Question

please just help answer a few math problems and please show how the hell you did it cause i dont understand it.

Simplify completely (-3p^4q^-2)^-5

write in standard form y= (2x - 3)(x+2)

write in vertex form y= x^2+9x - 7
and...
write in factored form y= x^2 + 11x - 60

Answer 1

(-3p^4/q^2)-5

1/(-3p^4/q^2)^5

q^10/(729p^20)




y = 2x^2 - x - 6




y = (x^2 + 9x) - 7
. . . . 9/2 = 4.5
. . . . 4.5^2 = 2.25
y = (x^2 + 9x + 2.25) - 7 - 2.25
y = (x + 4.5)^2 - 9.25




y = (x - 15)(x + 4)
