Solve for 25x2 + 9 = 30x

Mathematics
1 answer:
Irina-Kira [14]3 years ago
8 0

Answer: x=\frac{3}{5}

Step-by-step explanation:

Move all terms to one side.

25x^2+9-30x=0

Rewrite 25x^2+9-30x in the form a^2-2ab+b^2, where a=5x and b=3

(5x)^2-2(5x)(3)+3^2=0

Use the Square of Difference: (a-b)^2=a^2-2ab+b^2

(5x-3)^2=0

Take the square root of both sides.

5x-3=0

Add 3 to both sides.

5x=3

Divide both sides by 5.

x= 3/5
