Question

3x+2x²+4=5.
rewrite the equation in standard form and identify a and b. ​

Answer 1

Answer:

2x2 + 3x – 1 = 0; a = 2, b = 3, c = −1

Step-by-step explanation:

3x + 2x2 + 4 = 5

3x + 2x2 + 4 – 5 = 5 – 5

First be sure that the right side of the equation is 0. In this case, all you need to do is subtract 5 from both sides.

3x + 2x2 – 1 = 0

2x2 + 3x – 1 = 0

Simplify, and write the terms with the exponent on the variable in descending order.

2x2 +  3x - 1 = 0

(ax2) (bx) (c)

a = 2, b = 3, c = −1

Note that since the constant 1 is subtracted, c must be negative.

Answer 2

Answer:

${2x}^{2} + 3x - 1$

$a = 2$

$b = 3$

$c = - 1$
