Question

3x^2+5x+25, when x=3

Answer 1

[ Answer ]

`\boxed{121}`

[ Explanation ]

`3x^(2)` + 5x + 25

X = 3

Replace 3 For X

`3*3^(2)` + (5 * 3) + 25

Solve

5 * 3 = 15

3 * 3 = 9

9 * 9 = 81

Insert Numbers

81 + 15 + 25

= 121

`\boxed{[ \ Eclipsed \ ]}`

Answer 2

we have given that x = 3

so put the value of x in the given equation

`3 {x}^(2) + 5x + 25 \\ 3 ( {3}^(2) ) + 5(3) + 25 \\ 3(9) + 15 + 25 \\ 27 + 25 + 15 \\ 27 + 40 \\ 67`

so our answer is 67

Hope it helps
