What is the value of x^2 + 8x + 12 when x = -1

5

Step-by-step explanation:

x² + 8x + 12

x = -1

(-1)² + 8(-1) + 12

1 - 8 + 12

- 7 + 12

= 5

(-1)^2 + 8*(-1) + 12 = 1 -  8 +  12=  5

Step-by-step explanation:

answer: 0.1,0.85

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
