Step-by-step explanation:
ohhhhhhhhkkkkkkkkkkkkkkk
Answer:
⭐Question:-1
(2x – 3)(3x + 1) = 0
☯️Answer:-
1. [tex](2x – 3)(3x + 1) = 0 \\ [/tex]
[tex] = > \: 2x – 3 = 0 \: or \: 3x + 1 = 0[/tex]
[tex] = > \: 2x = 3 \: or \: 3x + 1= 0[/tex]
[tex] = \geqslant x = \frac{3}{2 \: } \: or \: x = – \frac{1}{3} [/tex]
[tex]hence \: the \: roots \: of \: the \: given \: question \: \\ are \: \frac{3}{2} \: and \: – \frac{1}{3} [/tex]
⭐Question:-2
4x² + 5x = 0
☯️Answer:-
2. [tex]we \: have \: 4x {}^{2} + 5x = 0[/tex]
[tex] = > x \: (4x + 5) = 0[/tex]
[tex] = > \: either \: x = 0 \: or \: 4x + 5 = 0[/tex]
[tex] = > x = 0 \: or \: 4x + 5 = 0[/tex]
[tex] = > x = 0 \: or \: x = \frac{ – 5}{4} [/tex]
[tex]thus,\: [/tex]
[tex]x = 0 \: and \: x = \frac{ – 5}{4} \: are \: two \: roots \: of \\ equation \: 4x {}^{2} + 5x = 0[/tex]
