Question

3-2x+5x²
pls answer ​

Answer 1

Answer:

$\sf\large5x ^{2} - 2x + 3$

By Quadratic Formula:-

$\sf\LARGE \frac{ - b +_-\sqrt{b ^{2} - 4ac} }{2a}$

Here, a= 5, b= -2,c = 3

$\sf\large\implies\frac{ - ( - 2) + - \sqrt{( - 2) ^{2} - 4 \times 5 \times 3} }{2 \times 3}$

$\sf\large \implies\frac{2 + - \sqrt{4 - 60}} {6}$

$\sf\large\implies\frac{2 + - \sqrt{ - 56}}{6}$

$\sf\large\implies \frac{2 + \sqrt{56} }{6} \: \: \: ,\frac{2 - \sqrt{56} }{6}$

Answer 2

$\huge \underline{ \underline{ \tt ANSWER}}$

3-2x+5x²

Now write it in simplest form:-

5x²-2x+3

By middle term splitting

5x²-5x+3x+3

5x(x-1)+3(x-1)

(5x+3)(x-1)
