Question

1. What is the value of 5x² – 3x + 5 when x=2?

Answer 1

Answer:

624 is the answer

Step-by-step explanation:

5x²-3x+5        x=2

plug in x=2: 25²-6+5=?

do the 25²: (25*25=625)

plug in 625 into the equation: 625-6+5

subtract 6 from 625: 625- 6= 619

plug 619 into your equation: 619+5=?

add 5 to 619: 619+5= 624
