Answer:
w=2, -3
Step-by-step explanation:
minus 25 from each side
1+-25+4w^2+4w=25+-25
combine like terms
-24+4w^2+4w=0
factor out the greatest Common factor
4(-6+w+w^2)=0
factor a trinomial
4((-3+-1w)(2+-1w))=0
I hope this helps!

Answer:
y = 3x - 7
Step-by-step explanation:
The <em>point-slope formula</em> for a straight line is
y – y₁ = m(x – x₁)
x₁ = 4; y₁ = 5; m = 3     Substitute the values
y – 5 = 3(x - 4)             Remove parentheses
y – 5 = 3x - 12             Add 5 to each side
      y = 3x - 7
The graph is a straight line with a y-intercept at y = -7 and a slope = 12/4 = 3.
