Solve for x 14 x square+7x-6
irina [24]

Answer:

x=0.450765 or x=−0.950765

Step-by-step explanation:

14x² + 7x - 6

→ Find the product, sum and factors

Product = -6

Sum = 7

Factors = No factors

→ Since there are no factors utilise the quadratic formula

\frac{-b+-\sqrt{b^{2}-4ac } }{2a}

→ List the values of a, b and c

a = 14

b = 7

c= -6

→ Substitute into the formula

\frac{-7+-\sqrt{7^{2}-4*14*-6} }{2*14}

→ Simplify

x=0.450765 or x=−0.950765
