Write the quadratic equation in standard form and then choose the value of "b." (2x - 1)(x + 5) = 0 9 10 11

2x² + 9x - 5

Here the value of b = 9.

Step-by-step explanation:

The standard form of a quadratic is . To write the expression (2x - 1)(x + 5) in standard form, multiply the factors using the distributive property and combining like terms.

(2x - 1)(x + 5)

2x²- x + 10x - 5

2x² + 9x - 5

Here the value of b = 9.

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be
