Question

find the value of below given expression. 4x^2+20x+25x, whenx=11​

Answer 1

4×11²+20×11+25×11

484+220+275

979

Answer 2

$4 {x}^{2} + 20x + 25x \\ 4 {x}^{2} + 45x\\ x = 11 \\ \\ 4( {11)}^{2} + 45(11) \\ 4(121) + 45 \times 11 \\ 484 + 495 \\ 979$

If it is 4x^2+20x+25

then

4(11) +20x + 25

484 + 220 + 25

=729
