Since 7y is common to both factors, therefore the GCF of the expression is 7y. The factored form will be 7y(3x + 2)

<h3>Greatest common factor of an expression</h3>

The greatest common factor is the value that will divide an expression without leaving a remainder.

Given the expression 21xy + 14y

Find the factors

21xy = 7 * 3 * x * y

14y = 7 * 2* y

From the factors above, it is clear that 7 and y are the greatest common factors.

Since 7y is common to both factors, therefore the GCF of the expression is 7y. The factored form will be 7y(3x + 2)

Factor out

  • 21xy=3×7×y×x
  • 14y=2×7×y

So

  • 7y is common hence 7y is GCF

Now factor up

  • 7y(3x+2)

Option B

Use the quadratic formula to solve 5x^2+2x-3
Lisa [10]
Assuming it equals 0
for
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}

given
5x^2+2x-3=0
a=5
b=2
c=-3

x=\frac{-2+/- \sqrt{2^2-4(5)(-3)} }{2(5)}
x=\frac{-2+/- \sqrt{4+60} }{10}
x=\frac{-2+/- \sqrt{64} }{10}
x=\frac{-2+/- 8 }{10}
x=(-2+8)/10 or (-2-8)/10
x=6/10 or -10/10
x=3/5 or -1
