Question

Plz answer the question. question 6.
​

Answer 1

Answer:

m=20

Step-by-step explanation:

If roots are equal delta=0

4x^2- mx+25=0

A=4, B= -m, C=25

Delta = B^2-4AC

0=(-m)^2-4×4×25

0=m^2-16×25

0=m^2-400

400=m^2

m=√400

m=20

HOPE THIS BRING A SMILE IN YOUR FACE

Answer 2

4x2-mx+25=0
Compare with ax2+bx+c=0
a=4 b= -m c=25

D=0
b2-4ac=0
(-m)2-4*4*25=0
(-m)2-400=0
m2=400
m=square root 400
m= +20 & -20
