Eddi Din [679]3 years ago

ANSWER

b=11

EXPLANATION

The given quadratic equation is

(2x - 1)(x + 6) = 0

We expand to get:

2 {x}^{2}  + 12x - x - 6 = 0

We simplify further by combining the x terms.

2 {x}^{2}  + 11x - 6 = 0

This is the standard form.

Comparing to

a{x}^{2}  + bx  + c= 0

We have b=11

Help!!<br><br> which expression is equivalent to (m^5 n /pq^2) ^4
lana66690 [7]
\text{Use:}\\\\\left(\dfrac{a}{b}\right)^n=\dfrac{a^n}{b^n}\\\\(a\cdot b)^n=a^n\cdot b^n\\\\(a^n)^m=a^{nm}\\\\......................................................\\\\\left(\dfrac{m^5n}{pq^2}\right)^4=\dfrac{(m^5n)^4}{(pq^2)^4}=\dfrac{(m^5)^4n^4}{p^4(q^2)^4}=\dfrac{m^{20}n^4}{p^4q^8}
