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
[tex]\frac{-b+-\sqrt{b^{2}-4ac } }{2a}[/tex]
→ List the values of a, b and c
a = 14
b = 7
c= -6
→ Substitute into the formula
[tex]\frac{-7+-\sqrt{7^{2}-4*14*-6} }{2*14}[/tex]
→ Simplify
x=0.450765 or x=−0.950765
Answer:
x=0.950 or -0.450
Step-by-step explanation:
14x^2+7x-6
using quadratic formula
x=-b+√b^2 -4ac/2a or x= -b-√b^2-4ac/2a
where b;7 ,a;14, c;-6
x=-7+√7^2-4(14)(-6)/2(14)
x=7+√49+336/28 or 7-√49+336/28
x=7+√385 /28 or 7-√385/28
x=7+19.621 /28 or 7-19.621 /28
x=26.621/28 or -12.621/28
x=0.950 or -0.450
