Question

Evaluate the expression when x=-5x²+6x-9​

Answer 1

Step-by-step explanation:

• x²+6x-9

When x= -5, then

• (-5)²+6×(-5)-9
• 25-30-9
• 25-39
• -14

Answer 2

Answer:

${x}^{2} + 6x - 9. \\ \\ solving \\ ( - 5) {}^{2} + 6 \times ( - 5) - 9 \\ 25 + ( - 30) - 9 \\ - 5 - 9 = - 14. \\ x {}^{2} + 6x - 9 = - 14.$
