Answer 1

Step-by-step explanation:

given. equation is divided by x^2-25

x value we have to find

${x}^{2} - 25 = 0 \\ {x}^{2} = 25 \\ x = \sqrt{25} \\ x = 5$

substitute x value in given equation

$= 3 {x}^{2} - 21x + 30 \\ = 3( {5})^{2} - 21(5) + 30 \\ = 3 \times 25 - 21 \times 5 + 30 \\ = 75 - 105 + 30 \\ 105 - 105 \\ = 0$
