Question

What is the value of 5x + 25 – 3x +32 + 2x-12 at x=1?​

Answer 1

Answer:

The value of it is -1

Step-by-step explanation:

Here we have been given an expression as below:

5x + 25 – 3x +32 + 2x - 12

Now here we have to find the value of this expression when x = 1

Hence putting x = 1 we have,

= 5 × 1 + 25 - 3× 1 + 32 + 2× 1 - 12

= 5 - 25 -3 +32 +2 -12

= 5 + 32 + 2 -25 - 3 - 12

= 39 - 40

= - 1

Therefore the final value of the expression at x = 1 is -1

Answer 2

Answer:

The value of $5x+25-3x+32+2x-12$  at  $x=1$  is  $49$ .

Step-by-step explanation:

We are asked to find the value of the polynomial $5x+25-3x+32+2x-12$

at $x=1$.

We can find it in two ways. Either just simply substituting $x=1$ in the polynomial, wherever $x$ is present.

That is

 $5(1)+25-3(1)+32+2(1)-12=5+25-3+32+2-12= 64-15=49$

Or we can further reduce the polynomial to

$5x+25-3x+32+2x-12=5x-3x+2x+25-12$

                                             $=4x+45$

now, at $x=1$ , $4x+45=4(1)+45=49$

Hence the answer
