Answer: A is 4
Step-by-step explanation:
Using the completing the square method to solve;
4x² - 20x + 3 =0
First take 3 to the right hand side
4x² - 20x = -3
Factor out 4, since 4 is a fctor of 4 and 20
The equation becomes;
4(x² - 5x) = -3
Therefore comparing this equaton with A(x² - 5x) = -3
A = 4
Answer:
A=4
Mariya was solving:
4x2-20x+3=0
4x2-20x=-3
A(x2-5x)=-3
At this point, we can know that 4*x2=4x2 and 4*5x=20x, son A=4
