Question

Fill in the blanks Part 1: Find the value of m so that the quadratic equation mx (x – 7) + 49 = 0 has two equal roots. The value of m is……….. *
(A) 1
(B) 2
(C) 3
(D) 4

Answer 1

Maybe d hope it help you

Answer 2

Answer:

m=2. I guess..

Step-by-step explanation:

mx(x-7)+49=0

mx²-7mx+49=0

comparing the above equation with

ax²+bx+c=0, we get

a= 1 , b= (-7m) , c=49

b²-4ac = (-7m)² - 4× 1 × 49

49m²-196=0

m²=196/49

m²=4

taking square root

m = 2
