3x^2 - 2x + 23
= 3(0^2) - 2(0) + 23
= 3(0) - 0 + 23
= 0 - 0 + 23
= 0 + 23
= 23
any term that multiply by zero equal zero.
So substitute the terms that have x with zero which gives:
23.
im assuming the x between 3 and 2 is just a multiplication sign, so you just put 0 in where the x is
3*2-2*0+23
3*2=6
2*0=0
6-0+23=6+23=29
Put simply, 0 multiplied by anything is 0. So, if x = 0, any term with an x in will automatically = 0. Which leaves 23!
i think your answer would be 23 because anything times zero is zero. so it's 3x0=0x2=0-2x0=0+23=23
23.
Substitute 0 for x. 3(0)2-2(0)+23
3 x 0 x 2= 0 - 2x0= 0
0-0+23=23
3x² – 2x + 23 if x = 0.?
= 3(0)² – 2(0) + 23
= 0 – 0 + 23
= 23
