The value of given expression is 341
Solution:
Given that we have to find the value of given expression
Given expression is:
[tex]4x^2 + 2x - 1[/tex]
Given value is x = 9
Substitute x = 9 in given expression
[tex]\rightarrow 4(9)^2+2(9) - 1[/tex]
Solve the above expression
[tex]\rightarrow 4 \times (9 \times 9) + 18 -1\\\\\rightarrow 4 \times 81 + 17\\\\\text{Multiply the terms 4 and 81 }\\\\\rightarrow 324 + 17\\\\\text{Add the numbers }\\\\\rightarrow 341[/tex]
Thus the value of given expression is 341
