Algebra expression: fifteen pages longer than a quarter the length of the first draft

Step-by-step explanation:

Let the original draft have length x.

Given that the new graph has pages equal to 15 more than the quarter length of the first draft

Quarter length of I draft =

To find 15 pages more we add 15 to this

15 more than the quarter length of the first draft=

So Algrbra expression for the requirement is

Verify:

From the length of new draft subtract 5 and multiply by 4. WE get length of original draft. THus our answer is correct

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
