Question

solve by factoruzation
25 m²=9​

Answer 1

Answer:

Given quadratic equation is 25m² = 9

25m² - 9 = 0

( 5m )² - 3² = 0

We know the algebraic identity,

a²-b² = (a + b)(a - b)

Now,

( 5m + 3 )( 5m - 3) = 0

5m + 30 or 5m - 3 = 0

5m= -3 or 5m = 3

m = -3/5 or m = 3/5

Answer 2

ANSWER

$25 m² =9$

$25 m²-9 =0$

$(5m)²-(3)²=0$

${(5m+3)=0 \: or \: (5m-3 )=0}$

${5m+3=0 \: or \: 5m-3 =0}$

$5m= -3 \: or \: 5m = 3$

$m = \frac{ - 3}{5} \: \: \: \: \: m = \frac{3}{5}$

roots of given quadratic equation are

$m = \frac{ - 3}{5} \: \: \: \: \: m = \frac{3}{5}$
