Question

find the zeros of the 5 x + 2 X square + 3​

Answer 1

Answer:

$2 {x}^{2} + 5x + 3 = 0 \\ 2 {x}^{2} + 2x + 3x + 3 = 0\\ 2x(x + 1) + 3(x + 1) = 0 \\ (x + 1)(2x + 3) = 0 \\ x = - 1andx = - 3 \div 2$

Hope its help you ❤

Answer 2

Answer:

2x^2+5x+3=0

2x^2+2x+3x+3 =0

2x(X+1) . 3(X+1) =0

(2x+3) . 3(X+1)=0

So,

2x+3=0. X+1=0

2x=-3. X=-1

X=-3/2

So the zeros are -1,-3/2
