Answer:
ig it Will be 8x-56 becoz 8 multiplies x and 7 and we get 8x-56
Answer:
2*x^3 + x^2 + x
Step-by-step explanation:
a^b = x
Then,
a^(2b) = a^b*a^b = x* x = x^2
a^(3b) = a^b*a^b*a^b = x*x*x = x^3
2*(a^3b) + (a^2b) + (a^b)
= 2*(x^3) + (x^2) + (x)
= 2*x^3 + x^2 + x
X^2 + 12x + 6 = -5
x^2 + 12x = -5 - 6
x^2 + 12x = -11
x^2 + 12x + 36 = -11 + 36.....u add 36 to both sides <=
(x + 6)^2 = 25
x + 6 = (+-) sqrt 25
x + 6 = (+-) 5
x = -6 (+-) 5
x = -6 + 5
x = -1
x = -6 - 5
x = -11
solutions are : x = -1 or x = -11
ur answer : add 36 to both sides.. ur x term is 12, take half of ur x term ,which gives u 6, then u square it, which gives u 36...and add that to both sides
