    Answer (if we’re solving for x):

    x=-7 or \frac{9}{2}

    Step-by-step explanation:

    1. Rearrange the terms from 2x^{2} =63-5x to 2x^{2}=-5x+63
    2. Move the terms to the left side: 2x^{2}-(-5x+63)=0
    3. Use the “sum-product” pattern: 2x^2+14x-9x-63=0
    4. Get the common factor drom the 2 pairs:2x(x+7)-9(x+7)=0
    5. Rewrite the equation in factored form as (2x-9)(x+7)=0
    6. Create 2 equations from (2x-9)(x+7)=0: 2x-9=0\\x+7=0
    7. This means that x can either be -7 (-7+7=0=x+7) or \frac{9}{2} (\frac{8}{2}=4; \frac{9}{2}=4.5)

    I don’t want to sound d u m b but use photomath it really helped me with quadratic formula it shows steps too.
