2 answers:
Answer: (3✖️- 7) (9✖️ +2)
Step-by-step explanation:
3^3 ✖️^2 -57✖️) - 14
27x2-57x-14 Final result : (3x - 7) • (9x + 2) Step by step solution : Step 1 : Equation at the end of step 1 : (33x2 - 57x) - 14 Step 2 : Trying to factor by splitting the middle term 2.1 Factoring 27x2-57x-14 The first term is, 27x2 its coefficient is 27 . The middle term is, -57x its coefficient is -57 . The last term, "the constant", is -14 Step-1 : Multiply the coefficient of the first term by the constant 27 • -14 = -378 Step-2 : Find two factors of -378 whose sum equals the coefficient of the middle term, which is -57 . -378 + 1 = -377 -189 + 2 = -187 -126 + 3 = -123 -63 + 6 = -57 That's it Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -63 and 6 27x2 - 63x + 6x - 14 Step-4 : Add up the first 2 terms, pulling out like factors : 9x • (3x-7) Add up the last 2 terms, pulling out common factors : 2 • (3x-7) Step-5 : Add up the four terms of step 4 : (9x+2) • (3x-7) Which is the desired factorization Final result : (3x - 7) • (9x + 2)

Answer:
infinite solutions
Step-by-step explanation:
4x=4x
Divide each side by x
4x/x = 4x/x
4 =4
This is always true,no matter what value we put in for x. So there are infinitely many solutions to the equation.
