Step-by-step explanation:
Solving a quadratic equation using factoring involves finding the factors of the equation that would yield the result of the quadratic equation
In order to find the roots of the quadratic equation, then the result of the factoring must be equal to zero, in which case, the constant terms in the factors are the solutions of the quadratic equation in opposite sign.
For example, we have;
x² - 5² = 11
We subtract 11 from both sides to get;
x² - 5² - 11 = 11 - 11
x² - 36 = 0
x² - 6² = 0
(x - 6) × (x + 6) = 0
Therefore, x = 6 or -6 which are the opposite sign of the constant terms in the factor.
We have that
−27x2yz5 + 15x3z3
we know that
27-------------> 3³
15-------------> 3*5
z^5-----------> z² * z³
x³------------> x² * x
substituting in the original expression<span>
−27x2yz5 + 15x3z3---------->[-3</span>³*x²*y*z³*z²]+[3*5*x²*x*z³]
[-3³*x²*y*z³*z²]+[3*5*x²*x*z³]-------> [3*x² *z³]*{[-3² *y*z²]+[5*x]}
the greatest common factor is [3*x² *z³]
Answer:
348
Step-by-step explanation:
9x8=72
9x6=54
8x6=48
72+72=144
54+54=108
48+48=96
144+108=252
252+96=348
Hence, counting the WHOLE surface are of the rectangular prism, the answer is 348
