Answer:
For step three she could multiply the two parenthesis against each other to get 3(x² - 10x + 25) - 2 + 4x
Step-by-step explanation:
step 1: 3(x - 5)² - 2 + 4x
step 2: 3(x - 5)(x - 5) - 2 + 4x
For step three she could multiply the two parenthesis against each other to get 3(x² - 10x + 25) - 2 + 4x
64 x 100 = 6400
11 x x = 11x
I’ll solve this out for you
11x = 6400
Divide 11 from both sides
x = 581.8

Answer:
m = 
Step-by-step explanation:
Given a quadratic equation in standard form ax² + bx + c = 0 ( a ≠ 0)
Then the discriminant Δ = b² - 4ac gives information on the nature of the solutions.
For the equation to have 1 solution we require b² - 4ac = 0
mx² - 6x + 5 = 0 ← is in standard form
with a = m, b = - 6, c = 5, then
b² - 4ac = 0
(- 6)² - (4 × m × 5) = 0
36 - 20m = 0 ( subtract 36 from both sides )
- 20m = - 36 ( divide both sides by - 20 )
m =
=
