Factor. 3x2 + 20x + 25​
algol [13]

Answer:

(3 x + 5) (x + 5)

Step-by-step explanation:

Factor the following:

3 x^2 + 20 x + 25

Hint: | Factor 3 x^2 + 20 x + 25 by finding factors of 3×25 whose sum is 20.

Factor the quadratic 3 x^2 + 20 x + 25. The coefficient of x^2 is 3 and the constant term is 25. The product of 3 and 25 is 75. The factors of 75 which sum to 20 are 5 and 15. So 3 x^2 + 20 x + 25 = 3 x^2 + 15 x + 5 x + 25 = 5 (3 x + 5) + x (3 x + 5):

5 (3 x + 5) + x (3 x + 5)

Hint: | Factor common terms from 5 (3 x + 5) + x (3 x + 5).

Factor 3 x + 5 from 5 (3 x + 5) + x (3 x + 5):

Answer: (3 x + 5) (x + 5)

7x^2=63<br><br> solve for x<br> please show work
o-na [289]

Answer:

x = ±3

Step-by-step explanation:

Step 1: Write equation

7x² = 63

Step 2: Solve for <em>x</em>

  1. Divide both sides by 7: x² = 9
  2. Square root both sides: x = ±3

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

7(3)² = 63

7(9) = 63

63 = 63

7(-3)² = 63

7(9) = 63

63 = 63
