Answer:
Yes the triangles are similar.
if you look at Angle C it's 60° and F is also 60°
60 + 67 is 127
127 + 53 is 180° which is the amount a triangle is. (assuming that E is 67°)
Well since we know the roots are x = 5 and x = -1/4. We can convert it into an equation and make it equal to 0.
Simply work backwards instead of solving for x. For x = 5, it would be x - 5 = 0, because if you solve for x it will be 5.
Same thing for x = -1/4, the equation would be x + 1/4 = 0.
(X-5)(x+1/4) = 0.
Now multiply the 2 binomials together to get the quadratic. To get rid of the fraction after obtaining the quadratic multiply by 4 for each term in the quadratic.
