Solve the equation x+1=2x for x. square both sides of the equation, and verify that your solution satisfies this new equation. show that −1/3 satisfies the new equation but not the original equation.

step-by-step explanation:

nswer: a   y-axis

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
