Question

The number of terms in the expression 2x² + 3x + 5 is ​

Answer 1

Step-by-step explanation:

2x²+3x+5

add 5 each side

2x²+3x-5+5=0+5

2x²+3x=5

divide both sides by x²

x²+3/2x=5/2

square of coefficients of x and divide by 4

(3/2)²/4=9/4/4=9/16

x+3/4=+-7/4

x1=1

x2=-7/4

x=1 or x=-5/2
