x = 3 ± F(X)=-2x²+12x-13 alguien me ayuda por favor, №18011037, 05.03.2020 04:23

Step-by-step explanation:

To find the roots of this equation, we can either use facotring or the quadratic formula. Because this equation isn't facotrable, we will use the quadratic formula to solve it

-2F(X)=-2x²+12x-13 alguien me ayuda por favor, №18011037, 05.03.2020 04:23 + 12x - 13 = 0

x = F(X)=-2x²+12x-13 alguien me ayuda por favor, №18011037, 05.03.2020 04:23

x = F(X)=-2x²+12x-13 alguien me ayuda por favor, №18011037, 05.03.2020 04:23

x = F(X)=-2x²+12x-13 alguien me ayuda por favor, №18011037, 05.03.2020 04:23

x = 3 ± F(X)=-2x²+12x-13 alguien me ayuda por favor, №18011037, 05.03.2020 04:23

x = 3 ± \frac{\sqrt{10} }{-2}

Step-by-step explanation:

To find the roots of this equation, we can either use facotring or the quadratic formula. Because this equation isn't facotrable, we will use the quadratic formula to solve it

-2x^2 + 12x - 13 = 0

x = \frac{-12 +- \sqrt{12^2 - 4(-13)(-2)} }{-4}

x = \frac{-12 +- \sqrt{144-104} }{-4}

x = -\frac{-12 +- \sqrt{40} }{-4}

x = 3 ± \frac{\sqrt{10} }{-2}

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.
