Answer:
D) 15/12 and 5/4
Step-by-step explanation:
Because when you cross multiply the ratios
15*4 and 12*5
making both ratios a proportion
they both = 60
<span>a, để pt có nghiệm thì denta ≥ 0 <=> (3-m)^2 - 4( 3-2m) ≥ 0 <=> m^2 +2m-3 ≥ 0 ( ^ là mũ)
giải bpt mới tìm được đó ta đc : m ≤ -3 hoặc m ≥ 1
b, * Xét m-1=0 <=> m=1 => thay m=1 vào pt thì pt có 1 nghiệm là 1/8 (1)
* Xét m-1 ≠ 0 <=> m ≠ 1
=> pt có nghiệm khi denta' ≥ <=> (m+3)^2 - (m-1)(-m+2) ≥0 <=> 2m^2 +3m+11 ≥ 0 (*)
-> bpt (*) có denta < 0 nên nó luôn đúng với mọi m ≠1 -> denta của pt đã cho luôn > 0 với mọi m ≠ 1 (2)
từ (1) (2) => với mọi m pt luôn có nghiệm </span>
