Solve this quadratic equation.<br><br> 6x2 - 2x = 7
rjkz [21]

Answer:

x₁ = (1 + √43)/6

x₂ = (1 - √43)/6

Step-by-step explanation:

6x² - 2x = 7

6x² - 2x - 7 = 0

Formula

ax² + bx + c = 0

a = 6 ; b = - 2 ; c = - 7

x₁/₂ = [-b ± √(b²- 4ac)]/2a

x₁/₂ = (2 ± √4 + 4×6×-7)/12

x₁/₂ = (2 ± √172)/12

x₁/₂ = (2 ± 2√43)/12

x₁/₂ = 2(1 ± √43)/12

x₁/₂ = (1 ± √43)/6

x₁ = (1 + √43)/6

x₂ = (1 - √43)/6

Help me with this question please
Lisa [10]
First find the equation of the line:

y - b = m (X - a)
y - 5 = 2/3 (X + 2)
3y - 15 = 2 (X + 2)
3y - 15 = 2x + 4
3y = 2x + 19

Then sub the y-value of A into the equation to find X.

y = 3
3(3) = 2x + 19
9 = 2x + 19
2x = 10
X = 5

And sub the X-value of B into the equation to find y.

X = -2
3y = 2(-2) + 19
3y = -4 + 19
3y = 15
y = 5
