Select the two values of x that are roots of this equation.<br> 2x2 + 7x + 6 = 0

SVEN [57.7K]

Hopes this helps:

Answer: x = -10/7

1. Simplify 2 • 2 to 4
4 + 7x + 6 = 0

2. Simplify 4 + 7x + 6 to 7x + 10.
7x + 10 = 0

3. Subtract 10 from both sides.
7x = -10

4. Divide both sides by 7.
X = -10/7

Which expression is equivalent to StartRoot 120 x EndRoot?.

Irina-Kira [14]

Here for 120, the expression for the start root and end root is given

$\sqrt{120} =2\sqrt{30}$

<h3>What will be the expression for start root and enroot of 120?</h3>

Here we need to find $\sqrt{120}$

By simplifying the given expression, we get:

$120=2\times2\times2\times3\times5$

$120=(2^{2} )\times3\times5$

by taking square roots on both sides we get

$\sqrt{120} =2\sqrt{30}$

Thus for 120, the expression for the start root and end root is given $\sqrt{120} =2\sqrt{30}$
