Question

- 14m -7 (2-m) =24. find m​

Answer 1

Answer:

Step-by-step explanation:

d=0 (real and equal roots)

d= b^2-4ac

0 ={2(m-12)}^2-4(m-12)(2)

=4(m^2-24m+144)-4(2m-24)

= 4{m^2-24m+144-2m+24)

=m^2-26m+168

=m^2-12m-14m+168

=m(m-12) -14(m-12)

=(m-12)(m-14)

=m=>12 &14

Answer 2

Answer:

-

Step-by-step explanation:

step-1.

-14m -7×2-7×(-m)=24

step-2

-14m-14+7m=24

step-3

-14m+7m-14=24

step-4

-7m-14=24

step-5

-7m=24+14

step-6

-7m=38

step-7

m=38÷(-7)

step-8

m=5.428
